mac: add an option to prevent focusing of the window on open

on macOS 10.15 setting the activation policy behaves quite weirdly. the
call changes the current active App to a nameless process, which
probably also the reason that prevents the not focusing to work.
a workaround for that, is to refocus the previous active app.

Fixes #7725
