Wrong gap size after toggling tab

[musjj]

To reproduce, with an empty workspace:

1. Open two new windows, horizontally aligned (they should belong to the same group)
2. Focus the left window
3. Run hyprctl dispatch hy3:makegroup tab
4. Run hyprctl dispatch hy3:changegroup toggletab
5. The gaps between the two windows are bigger than normal

The gaps go away with hyprctl dispatch hy3:movewindow r. Not sure if I'm doing anything wrong here.

I think I understand what's going on, it's because the group still exists. I guess this isn't really a bug.
