Opening a new-tab after a split-pane causes two tab bars being highlighted

Other Software

No response

Steps to reproduce

Run the following command:
wt ; split-pane -H ; new-tab

OR, for a better visual understanding:
wt --title wrong-tab --tabColor "#ff0000" ; split-pane -H --title wrong-tab --tabColor "#ff0000" ; new-tab --title correct-tab --tabColor "#04ff00"

Expected Behavior

Only one tab bar highlighted. The one from the last command.

Actual Behavior

Two tab bars highlighted.

After switching between tabs or hovering the wrong highlighted tab bar, it fix itself.

Man those are some great repro steps. Thanks!

I'm guessing this is related to whatever's causing #8948. That's what we get for hot-swapping XAML resources like this 😝

Hey guess what, I think this is just going to be fixed by magic by #11720
