AR: Instant multi-GB continuous memory increase
ER: Not so

Bisection: bug 1906679

In full-screen window, the memory rise is so rapid that you cant capture any profile or about:memory.
But of you reduce the window size, the memory rise is less rapid (though still quite fast).
I managed to capture a profile with the "webgpu" preset logging: https://share.firefox.dev/3zPyEaY
