Comment 5

[David Shin[:dshin]]

Can repro locally with ./mach web-platform-tests --headless --chaos 251 ./testing/web-platform/tests/css/selectors/invalidation/is-pseudo-containing-sibling-relationship-in-has.html fairly consistently.
Two failure points, both locally and on treeherder.
Very strange, results of these should not change until bug 1792501 closes.

Comment 6

[Emilio Cobos Álvarez [:emilio]]

Which platform and which build config? I tried this on a regular debug build and can't repro...

mach wpt --headless --chaos 251 ./testing/web-platform/tests/css/selectors/invalidation/is-pseudo-containing-sibling-relationship-in-has.html --repeat-until-unexpected

Goes for iteration 50 and still nothing...

Comment 7

[David Shin[:dshin]]

... Huh, interesting. I am on Ubuntu 20.04.6

ac_add_options --enable-debug
ac_add_options --disable-optimize

Comment 8

[Emilio Cobos Álvarez [:emilio]]

Okay, I have an optimized build but can try without optimizations...

Ah, thanks! So, yeah, the parser hasn't inserted those yet, but we've yielded to be able to display the page.

If you wait a bit in the trace, then you see them come. So it's effectively an invalidation bug, but I don't think there's anything more magic about it.
