ToggleFullscreen does not work.

Alacritty 0.15.1 via Deb 13 repo.
Regardless of keybinding, ToggleFullscreen does not work.
I've confirmed; I do not have a competing system-level keybind.
Unless I'm doing something grossly wrong in my config ...
While it's not a direct duplicate of [#6647](#6647), it does seem similar.
