…ere() in subject position. r=firefox-style-system-reviewers,jwatt,dshin The page has selectors like: ``` :where(._space-y-6_caiht_2 > :not(:last-child)) ``` Unfortunately our current code to collect ancestor combinators doesn't deal with this case which means that we don't fast-reject these on things like <head>. This causes the <html> element to get the slow selector flags, which causes patterns like the one in comment 4 to restyle the whole <body> over and over which is super slow.

…nursery invariant r=jandem This table has the invariant that all the tenured views come first, with the position of the first nursery view being recorded to allow efficient access to only the nursery views. This did not account for semispace nursery where some nursery views can remain in the nursery after minor collection. The fix is to move any subsequent tenured views before the first nursery view seen and update the recorded position of the first nursery view. The invariant is checked after sweeping in debug builds.

…ttachFunction. r=iain It's simpler to use a specialized stub for the primitive-LHS case. This avoids changing the function's shape and fixes the assertion failure in the bug. The micro-benchmark in bug 1994205 is still fast. It's a bit faster even because we emit better code for the primitive-LHS case now.

…ore trying to call it. r=morgan UiaRaiseNotificationEvent is only available on Windows 10 version 1709 and later. Previously, we tried to call it without checking whether it was available, causing crashes on (very) outdated versions of Windows 10. We now explicitly check whether this function is available before trying to call it, gracefully doing nothing if we can't. Differential Revision: https://phabricator.services.mozilla.com/D303249
… r=eeejay Previously, we used the IsPrinting flag on the BrowsingContext in some cases to check whether a document was a print document. While IsPrinting will always be true on a print document, it might also be true for the original document (as opposed to the static clone) while it is being printed. This caused us to use the PDF cache domains in some cases when we shouldn't and might have caused other problems down the line. To fix this, check whether the document is a static clone instead. Accessibility should only ever see a static clone if it's a print document, but we assert IsPrinting to be sure. Differential Revision: https://phabricator.services.mozilla.com/D303299
… to update the cache domains for print documents. r=eeejay Print documents use a specific set of cache domains, so they shouldn't be impacted by any changes to the global set. I haven't seen any bugs show up because of this, but it's definitely a correctness issue that should be fixed. Differential Revision: https://phabricator.services.mozilla.com/D303300

…r handling of WeChat Input Method r=m_kato When we return `TS_E_NOLAYOUT` from `ITextStoreACP::GetTextExt()`, WeChat Input Method does not handle the error correctly and shows its UI to the top-left corner of the screen. Therefore, we need not to return `TS_E_NOLAYOUT` if it's the active TIP. However, I found 2 extant bugs and they block fixing this bug. First one is, `TSFTextStore::MaybeHackNoErrorLayoutBugs()` does nothing if `IsHandlingCompositionInContent()` return `false`. [1] This means that we don't hack `GetTextExt()` behavior when the composition starts and not yet dispatched the first event. So, this causes temporarily appear the UI in odd place, like top-left corner of the screen even with some other IMEs. The other one is, `TSFTextStore::GetTextExt()` may query a line break rect when the user starts composition at end of a line. [2] So, only when starting composition, the UI may (maybe temporarily) appear at start of next line. Therefore, if the line scanning range in the original content has a linefeed, we should query a rect before the first linefeed, i.e., only the text rect in the start line even if it's 0-length. The difference between the caret rect and the new character rect should be smaller than the difference from the start of the next line. 1. https://searchfox.org/firefox-main/rev/e28b34ab33dbf49364999070168cbb7e11e8e5bd/widget/windows/TSFTextStore.cpp#2156,2172,2175 2. https://searchfox.org/firefox-main/rev/e28b34ab33dbf49364999070168cbb7e11e8e5bd/widget/windows/TSFTextStore.cpp#2070 Differential Revision: https://phabricator.services.mozilla.com/D303266

…t string r=flod,fluent-reviewers DONTBUILD flod left a comment on D301981 noting the new menu-view-open-tabs string is missing the same "Open tabs" disambiguation comment the other Open Tabs strings carry, so translators know "Open Tabs" is a noun phrase (the tabs currently open) and not an instruction. Same pattern as sidebar-menu-open-tabs-label and sidebar-opentabs-title. Just a comment addition. Differential Revision: https://phabricator.services.mozilla.com/D303685

… r=sheehan,sparky,perftest-reviewers DONTBUILD This allows `mach try` calls to use a unique entry point to handle defaults and env-based overrides for all uses (currently try pushes to lando, and `perf`). This also fixes a latent bug where the LANDO_TRY_CONFIG override would return an incorrect value when used with `mach try perf`.

…llback-string globals. r=iain LLMs keep finding clever ways to mutate the interrupted code. It seems better to create the global with a small set of allowlisted testing functions to prevent this. The functions to trigger GC seem most useful because that's what interrupt callbacks can do in the browser. Differential Revision: https://phabricator.services.mozilla.com/D303359

I don't know if we've been flagging additions to the schema that don't have the extra properties we've added in the enterprise branch. @bsmth I have recommended that the additional properties be upstreamed so that we don't have to be the ones to deal with them.

Maybe it's time to enforce this via linter upstream, i.e., #910
