Let's await #77299 having landed.

[primeos]

Update: #77299 is merged and already in nixos-unstable by now.

@flokli should we merge this PR first or directly test #78603? And do you know if we have a "standardized" (working) procedure for Chromium backports (e.g. are backports usually fine when they're fine on master or do we have to re-run all/some tests)?

@mebubo just a quick FYI: Please cherry-pick with the -x option, if possible, to reference the commit from master.

Update: The AArch64 build is failing due to the patches but this is already the case without this PR (i.e. no new regression): https://hydra.nixos.org/build/110325603 - I've included the existing fix in #78603.

[primeos]

Closing this PR as I've just merged #78584 and we should therefore focus on #78603 now.

Thanks for the hint @primeos, I'll be using it :)
