[Launcher] Pending argument validation is not reset if the Launcher gets hidden

When using a "multiple choice" command, it is unclear wher the user is as the first part of the command isnt shown, also when closing and reopening the launcher (by clicking outside the window) the launcher opens where it was in the multichoice, making it unclear for the user.

(at the end I hit escape to get out of the set source context)

Steps to reproduce

• In launcher type set source branch
• Close launcher by clicking outside the window
• Relaunch launcher (in my case clicking the bubble, not sure if it does it with the shortcut)

the launcher is still set to set source > branch

Suggestions

• It would make the "navigation" clearer if set source > branch was displayed in the launcher ui
• Maybe the launcher should get reset when closed and reopened?
