Flatpak Celluloid doesn't close files properly.

[Fraetor]

Overview Description:
The Flatpak version of Celluloid doesn't properly close the file after being closed, which means that if you then delete the file it the space is not reclaimed.

xdg-document-portal is the process holding onto the file.

Steps to Reproduce:

1. Play video with Flatpak Celluloid.
2. Close Celluloid, and delete the video. It makes it easier to locate in the next step if your rm video.mp4 directly.
3. list open, but unlinked files with lsof +L1 | grep xdg, and see if your video file is there.

Actual Results:
The file remains open even after celluloid has closed and the file has been deleted.

Expected Results:
The file is closed, and the space it occupied is released.

Version:
0.23 Flatpak

Additional Information:
This might very well be a bug in Flatpak, but I though it was worth asking here first.

Yeah. This looks more like a bug in xdg-desktop-portal.

This issue (flatpak/xdg-desktop-portal#689) is now fixed upstream with flatpak/xdg-desktop-portal#1190.

This has been released in xdg-desktop-portal 1.18.2.
