Steps to reproduce:
- Open a page that will show a notice in VE (e.g. old version of a page, protected page, etc.)
- Open a toolbar dialog while the notice is still shown (e.g. press Crtl+F, or open the special characters and manually show the notice again.)
The notice should be above the dialog.
The content of the dialog is shown above the notice, partially obscuring it in a strange way.
