Title:
  When switching tabs, 'Loading...' with spinner doesn't disappear after
  tab data was loaded first time

Status in OpenStack Dashboard (Horizon):
  Expired

Bug description:
  Bug appears on horizon 2013.2. So i switch to some tab, it loads its
  contents from the server, but after the GET request is completed,
  'Loading...' string with spinner do not disappear. If I then switch
  back to some other tab and then to the tab with hanging spinner, it
  successfully shows its contents.

  I found the code responsible for tab loading,
  static/horizon/js/horizon.tabs.js:18. So if I place a breakpoint (in
  Chrome Web Tools) onto line 20, then continue execution, the desired
  tab contents appears even when I switch to it first time. Seems like
  an async issue - javascript doesn't have enough time to update the
  DOM. Also, it wasn't reproduced on slower machines.
