brave-browser: Gnome Wayland Fractional Scaling Regression

Description

Previously brave worked fine when org.gnome.mutter experimental-features was set to ['scale-monitor-framebuffer'] (necessary to get fractional scaling at the moment under gnome). Now if you set the display scaling to something larger than 100% (e.g. 150% or 200%), brave is not scaled properly, appearing much too large.

Steps to Reproduce

1. gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
2. Set display scaling to something larger than 100%
3. Install latest version of brave
4. Set Preferred Ozone platform to Wayland under brave://flags
5. Restart brave

Actual result:

Brave window is not sized properly, e.g. when it is “maximized” it takes up more than the full screen and is blurry.

Expected result:

Brave is sized properly according to the desktop scaling setting and not blurry.

Reproduces how often:

Consistently
