Description of the issue:
The upper right settings menu button is not showing when using QT-theme.
However this might be more of a feature than bug? One can still access settings by typing “settings” in the url-field.

How can this issue be reproduced?

  1. Settings > Apperance
  2. Change theme to QT

Expected result:
Settings button visible/accessible
QT-specific buttons should show hover-tooltip
