[Bug 1576605] Re: Activating menu items creates permanent space between title bar and tabs

** Tags added: apport-collected xenial

** Description changed:

  This bug applies to all Firefox versions since Unity brought global
  menus. However, only Firefox is affected, I've not observed any other
  app with a similar issue.
  
  What I expected:
   * Activating a menu item to simply display the relevant menu and cause no further interface changes
  
  What happened instead:
   * Activating a menu item displays the relevant menu and introduces a space between the titlebar and tabs
  
- The change is persistent as long as the window is open. Resizing or
- maximizing makes no difference. Enabling and activating menus from the
- title bar causes the exact same effect. Closing the window and reopening
- it from History's "Restore Closed Windows" removes the space. In other
- words, it does not affect newly opened windows.
