Moving audio file while previewing does not work

[AmonBune]

Steps to reproduce

1. Click on the filename of a music file (.flac, .mp3, etc.) -> audio file preview plays
2. Click on the [...] on the right side and then "move or copy". Select a folder.
3. Error: "Could not move "music.flac"

Expected behaviour

Either: The audio file preview stops playing and the file gets moved
Or: The audio file preview stops and continues after the file got moved

The error seems to be a lock that is currently on the file (because it is being played).
