Redundancies and glitches in "select"

Configuration Frontend
1
  • Clicking on the “all” checkbox goes to indeterminate before going to selected:
    screencast
  • The “select” menu
    image
    can all be accomplished other ways (by using the x button to close and the “all” checkbox for selections)

Is this expected behavior with a good reason, or should I go file some issues on the frontend repo?
