Created attachment 374680 [details] bug reproduction When creating a webgl context and drawing form video texture a few weird things happen: 1. max active contexts limit is suddenly 8. 2. creating an additional context returns `null`. 3. creating *another* context crashes the tab, and causing a refresh. Seems to be happening on Safari on all platforms. I have created a reproduction of the bug in a simple webgl program that creates context, loads videosm and draws a frame, on every button click. First 8 clicks work fine. 9th click returns `null` (instead of a new recycled context) and causes an error. 10th click crashes the tab, after trying to recycle the same context from before and printing: `WebGL: INVALID_OPERATION: loseContext: context already lost`. Also attaching the error log.

Ping, it's almost 2 years now. Any chance someone can take a look?
Created attachment 431439 [details] Testcase - works for me I tried to reproduce it with a refined test-case and things seem to work as expected, maybe something is missing in the test case?
Thanks Noam! Seems to be fixed in Safari 14.1.1
