context lost, firefox vs chromium browser on very large models on windows

[Vr]

Noticed firefox is able to load a lot more then chromium based browsers on windows before I get context lost.

Is it a bug, or is just firefox better on memory ?
Tried to switch angle backend/turned of memory saver etc

Tried to make weird little sample here.

On PopOS and chromium browser Im able to click the click add 50 button and do it again in a new tab. If I do this on window, it will fail, firefox have no issues.

Tried similar on 3 laptops, and firefox just handles it a lot better.
Tried newest edge/chrome/brave.
