Previously, on the Extension packages page, clicking Enable on several MKPs in quick succession produced a success flash message for each, but only the first MKP was actually enabled.

The same also affected the Disable button.

This has been fixed: clicking Enable or Disable on one package now locks the corresponding buttons on the other rows for the duration of the action, so only one extension package operation can be in flight at a time. To enable multiple packages, wait for the page to reload after each action.
