Bug description

The screen times-out during playback. The inhibit request is sent correctly, but it is released about five milliseconds later, long before playback ends. This is not a Flatpak sandbox issue — the D-Bus permissions are
present and the call reaches the bus successfully.

Steps to reproduce

1. Open any stream in Nuvio (doesn't matter if in full-screen or not).
2. The screen times-out after a while.

Expected behavior

The idle inhibitor stays registered for the duration of playback.

Actual behavior

The inhibitor is created and then immediately removed by the session manager, because the connection that requested it has already closed.

Frequency

Always

Is this why my screen always locks itself (and falls asleep if left long enough) whenever I'm tryna watch stuff.. It gets extremely irritating
