Changing colors in traditional MacOS fullscreen displays titlebar

[russelldavies]

Describe the bug
When using Kitty in traditional MacOS fullscreen mode and changing colors via a keyboard shortcut the titlebar suddenly shows up. Exiting fullscreen mode and reentering it shows no titlebar (until the colors are changed again).

To Reproduce
Steps to reproduce the behavior:

1. Add the following to kitty.conf:

macos_traditional_fullscreen yes
map f1 set_colors --all --configured .config/kitty/themes/theme1.conf
map f2 set_colors --all --configured .config/kitty/themes/theme2.conf

3. Launch Kitty and enter fullscreen.
4. Press F1 or F2 and title bar appears.

This occurs on versions of Kitty 0.34.0 onwards. Versions 0.33.1 and below are not affected.
