Changes (by alsroot):

  * keywords:  => r?
  * version:  Unspecified => Git as of bugdate
  * milestone:  Unspecified by Release Team => 0.86


Comment:

 In my mind correct fix could be too invasive for 0.86,
 but this issue have odd consequence:
 |TestCase|
 * open journal entry palette
 * open "Resume with" submenu
 * not closing palette and submenu, fast right click on another Journal
 entry
 * palette should be closed but submenu still exists

 So, minimal fix could be just hiding submenu(but it still doesn't have
 predictable behaviour since __enter_notify_event_cb() doesn't invoke
 on_enter()) but it could be enough for 0.86(we have similar situation with
 comboboxes).
