The Bugbug bot thinks this bug should belong to the 'Core::Canvas: 2D' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It seems that client WebGL textures get GC'd way later than is really useful,
so we need to ensure that we explicitly delete WebGL textures to ensure that
it happens in a timely fashion.

Hello there! I tried to reproduce this issue on Firefox 100.0, Win10 x64 bits, but the URL provided by the reporter is unresponsive. Instead I reproduced the memory usage issue using this link (link provided from a dupe of this bug). Memory increase up to 90% in Task Manager.
I verified the fixes in Firefox 102.0b5(20220607212916) and Nightly 103.0a1(20220608214824) on Win10 x64 and the memory drops significantly - around 50% maximum.
Given the fact that memory usage dropped by about half, I assume this would be the expected behavior of the fix?
Thank you.
