Reloading configuration on macOS can get the tab bar stuck in light mode

[Samasaur1]

When the following conditions are true:

• macOS
• light and dark themes set
• in dark mode

and the configuration is reloaded, the tab bar gets stuck in light mode for all newly-created windows and when new tabs are added to existing windows.

Reproduction:

1. Set your ghostty config to this:

   theme = light:catppuccin-latte,dark:catppuccin-mocha
   

2. Quit Ghostty
3. Switch to Dark Mode
4. Reopen Ghostty
5. Reload configuration (shift-command-,)
6. New tab (command-t)
7. The tab bar should now be in light mode

To temporarily fix the issue, switch into light mode and then back into dark mode

I'm able to reproduce this on Ghostty 1.0.0 (commit 4b4d406) with a config file made up of the above snippet and nothing else

This same behavior also seems to happen when the system theme changes while my computer is asleep
