Memory usage

Basically we are having a video (getUserMedia) and mirror it into a canvas. As long as the canvas is not appended to the DOM, we have a memory leak.

After 40 seconds Safari reloads the page...

Funny, we are having 18446744073,98 GB of RAM! (See screenshot in attachment)


Reproduction: https://jsfiddle.net/mkn2tb3h/
Device: iPad 8
iOS: 15.0 (19A5337a)

Kind regards,
Maximilian Böhm
