"Lint groups" picker has inconsistent nothing-selected behavior.

[kpreid]

Description

One of the options in the "Lint groups" menu is "None", which deselects everything. But if you have only one group selected and click it, it resets to default.

• This is inconsistent UI; either
  • nothing-selected should be permitted however you reach it, or
  • the "None" option should not exist.
• This is inconvenient and unpleasantly surprising when my goal is to view one group at a time, and the obvious thing to do is to uncheck the selected group and then check the next one in the list.

This is a weird bug, it appears to be very inconsistent for me. Most of the time, it will work as expected, but sometimes it resets the view to the default selection.
