Hi Team, Thanks for your continuous support and fixing so many bugs. I came across another reproducible crashing test case and I want to bring it to attention, so it can be fixed. GitHub Repo Link - https://github.com/mrk-its/bevy-atari/issues/20 Test Link (To Crash) - https://mrk.sed.pl/bevy-atari/#disk_1=https://slawson.org/atari/sigils/sigils.atr *** STEPS TO REPRODUCE *** 1) Open Test Link 2) Splash of screen and crash within few seconds and it happens every time << EXPECTED RESULT >> It should not crash tab - Safari 15.6 and Safari Technical Preview 150 << ACTUAL RESULT >> It crashes Safari 15.6 but does not crash Safari on iOS 15.6 using iPhone 13 Pro Max. ___ NOTE - All other browsers load this test page fine similar to iOS 15.6 Appreciate if you can look into it and fix this crash. NOTE - I have selected 'JavaScriptCore' initially since it is using WASM on test page and also IndexedDB. Looking forward to another crash being fixed. Thanks!

NICE! Reproducible crash test is treasure. We are crashing on WebGL. I've changed the title and component.
