Custom title is not restored when tab overview is closed via creating a new tab

[gzusseat]

Creating a new tab from the overview sets the title to Ghostty even though i have title = " ". If I click on an unfocused tab it disappears again. bug?

Can't reproduce in 1.1.2 (launched with --title=" ").

Your headerbar clearly says Ghostty. Now try launching a new tab from the headerbar/window decoration + sign. It doesn't add Ghossty in the headerbar title.

I use Arch-->Plasma btw.

Oh that. Yeah I think that's a bug. We might be forgetting to restore the window title when we're switching back from the tab overview.

I'll leave it to you to open an issue for this @pluiedev if you confirmed it.
