After renaming a model viewport or layout in the bottom bar, keyboard focus is not returned to the command bar. I have to click back into the viewport before I can type a command.
The same thing (loss of command focus) happens when clicking one of the navigation arrows that appear when there are too many layouts to fit on the screen. It also happens if I open the right-click menu on the current layout and select something or dismiss with ESC.
Switching to a different layout does return focus to the command bar, but that seems to be a special case that isn’t triggered by other interactions with this bar.
