Title: Don't tab to WindowCommand group, only commands

Previously if the user added WindowCommands to TitleBar (like
"Settings", "Help", etc.) tabbing would first select the group of all commands
before selecting individual buttons. Like so:

Since (amusing as it would be) it doesn't really makes sense to press all the things at once,
this PR makes it so tabbing **only** goes through individual buttons.
