Kitty taking over the workspace on startup even though I didn't ask it to

[5GameMaker]

Only happens when a new instance of Kitty is opened, but not if a new window is spawned via a keybind.

Not a issue with the config file - the behavior still occurs if I comment it out. Not an issue with my version of Kitty - I built Kitty from git and same behavior occurred (both master and gpu). Nothing in Hyprland config either - the only window rules related to Kitty are the default ones that are also by default commented out. Also happens on my other machine (with near-identical configuration).
