Description

When switching between two fullscreen windows within the same workspace, Firefox tries to resize itself, causing an ugly stretching animation. This issue does not occur when switching workspaces—Chrome and other applications do not resize themselves. The resizing behavior is inconsistent, making fullscreen window switching look jarring and unpleasant.

How to reproduce

Steps to Reproduce:

1. Open two windows in the same workspace.
2. Toggle fullscreen (SUPER + F) on Firefox.
3. Use ALT + TAB to switch between the two fullscreen windows.
4. Notice that Firefox resizes itself briefly before rendering properly.
   NOTE: i have a keybinding to toggle fullscreen and cyclenext to cycle between windows in same workspace
