The video player `value.isBuffering` returns true as soon as a video finishes playing on android

### Steps to reproduce

1. Start a Video via Network URL
2. Let the Video finish
3. The loading spinner will appear, meaning the `isBuffering` variable got true
4. After a long wait time, the `isBuffering` value changes to false

### Expected results

If a video finishes, it should not be buffered anymore, so `isBuffering` should stay `false`.

### Actual results

`isBuffering` changes to `true` after the video finishes and stays `true` for a long time (about a minute).
I think this might be related to a previous issue #165149.
