Block KDE Connect as media session
Summary
Block the "KDE Connect" media session (created to control your desktop's MPRIS player). This prevents loops etc.
To me, it didn't make sense to re-export your MPRIS anyway.
Test Plan
Before:
"KDE Connect" appears in the player list (when the plugin is actually enabled, of course).
After:
"KDE Connect" doesn't appear anymore, other media session still do.
