Allow to close popups on Catalyst via clicking on semitransparent space

[roman901]

Description of my issue or feature request:

Currently, if I open Settings or contact details, I must click directly to Close button to close it. Many sites/apps uses "click to modal background to close" pattern which is intuitive.

System information (if you can provide):

macOS version: 5.0 beta

This seems to be non-trivial
