Check / fix table border color in dark mode

[alya]

As a follow-up to zulip/zulip#29856, we should see if it's worth tweaking the table border color in dark theme in the mobile app.

Implementation notes:

The first step here is to see if the issue reproduces in mobile. If tables in dark mode already look fine and don't have this issue, then we're done.

If the issue does reproduce, then we should be able to fix it by just copying whatever CSS change is made to fix it in web.

The webapp issue has been resolved in zulip/zulip#29859.

Cool, thanks for the update.

It looks like the key change was in this commit: zulip/zulip@8a9fb04
and changed the border color from hsl(0deg 0% 0% / 20%) to hsl(0deg 0% 100% / 20%).

It kind of sounds like this might have been a regression caused in the first place by some other changes — it looks like what happened is that some CSS that was meant for a different part of the UI was too broad and consequently applied also to tables in Markdown content. So that suggests the issue might not exist in mobile. We'll find out as the first step in this issue, as mentioned above.

I'm not sure this is a priority for the legacy app? In any case, removing the release goal label, as it's not specifically timely for 9.0.

Yeah — I think as long as this isn't something we feel we're likely to highlight in the 9.0 announcement (and I suspect it isn't), it isn't a priority for the legacy app.
