macos-titlebar-style=tabs tabs disappear when system switches between dark and light mode.

[smsegal]

With macos-titlebar-style set to tabs and a seperate dark and light theme set will cause multiple tabs to appear to merge into one when the system switches between dark and light mode.

The tabs can still be switched between via keybindings, but the mouse cannot be used to switch between them.

Further update: If my background opacity is set to 1 (i.e no transparency) the issue doesn't occur.
