A very very bad bug !

[jls28]

The story :

I made an nice Win32/Win64 app using webview2
and this app was very reliable before I meet this bug.

The BIG problem with this bug is
than it only happen without a debugger (and close abruptly my app) :
when running with the VS2022 debugger this bug never happen !

so I worked hard and used ASAN and Dbgview and I localized the problem:

the problem is than for some navigations sequence
I get a
WebResourceRequested event
with a get_Source returning an empty string (the context is COREWEBVIEW2_WEB_RESOURCE_CONTEXT_PING),
(I writed my code assuming than get_Source never could return an empty string)
and badly this event never happen when using the VS2022 debugger.

to reproduce (don't use a debugger) :
Navigate("data:,test")
then
Navigate("https://www.google.com") <- here WebResourceRequested with get_Source empty and COREWEBVIEW2_WEB_RESOURCE_CONTEXT_DOCUMENT
GoBack() <- WebResourceRequested with get_Source empty and COREWEBVIEW2_WEB_RESOURCE_CONTEXT_PING ONLY WITHOUT DEBUGGER

note : the WebResourceRequested even with get_Source empty and COREWEBVIEW2_WEB_RESOURCE_CONTEXT_DOCUMENT
happen with the VS2022 debugger.
