Single instance Kitty windows freeze when a window is obstructed by tiling

[Scrumplex]

I have bisected this bug. Commit 60d33f2 introduces this.

Describe the bug
When I have two single instance Kitty windows open and one of them is "hidden" by switching my tiling mode to Tabbed on Sway, all windows of that Kitty instance freeze and don't render new frames.

To Reproduce
Steps to reproduce the behavior:

1. Open two Kitty windows using single instance mode
2. Move one window to a separate workspace alongside some other arbitrary window and "hide" it by switching to a stacking/tabbed layout
3. Try to interact with still visible window
