z-index of contextmenu is higher than z-index of timeout-overlay
|Priority:||Could have||Due date:|
When you open the contextmenu of a page in the page tree and wait a long time until the session times out, you get an overlay. This overlay hides the page with some alpha-transparent layer and shows a dialog to enter your password and stay logged in.
This overlay has a lower z-index as the contextmenu. So the contextmenu is still clickable and isn't grayed out.
Fix should be easy: Either adjust z-index of overlay and dialog or adjust z-index of contextmenu.
