Crash with stylesheets in shadow dom
Working on a demo, getting relatively consistent crashing while working with it. Crashes have occurred on page load and while running performance devtools.
Any crash reports or any more information here?
So far no luck reproducing. And in crash-stats.mozilla.com I see very similar crashes on 52 Thunderbird. Somehow we have null mSheet
No longer blocks: shadowdom-initial-release
Emilio is more familiar with stylesheet loading.
I couldn't repro either... Any reliable str Potch? SheetLoadData::mSheet is not supposed to be null...
I can't think of reliable str, I'm working with the example code (making changes, refreshing, profiling) and I lose the tab relatively frequently. No crashes on my nightly outside of this. The following reports are all from working with the above demo: https://crash-stats.mozilla.com/report/index/bp-ca73d3cb-a3b4-4eba-88c0-ef4580180712 https://crash-stats.mozilla.com/report/index/bp-6066e7a3-23c1-4005-a682-dda1b0180712 https://crash-stats.mozilla.com/report/index/bp-51a48b50-30f0-48d8-a199-d91e40180712 https://crash-stats.mozilla.com/report/index/bp-257341e4-82e3-4f38-abec-4fb6e0180712 https://crash-stats.mozilla.com/report/index/bp-450e6a80-bbc8-45b8-beaf-557960180711 https://crash-stats.mozilla.com/report/index/bp-62a79a01-64b1-4314-9b35-588d30180711
Ah, I managed to repro with the inspector open.
