While playing a video (.mkv and .mp4) with multiple subtitle tracks, changing the subtitles track when the video has ended, the seek bar is reset and play/pause button is showing pause and the video is not playing. Pressing the play/pause button does nothing. The only workaround I found was, I had to move the seek bar slider forward and backward then the video played. (video attached)

Steps to reproduce:

1. Open example "multimedia/video/mediaplayer" (Qml Video player example)
2. Build it and run it
3. Open a video which has subtitles attached to it (test video also attached)
4. Run the video and let the video end
5. Go to settings and select the other track

Expected Output:

The video restarts or pressing the play/pause button, starts the video.

Actual Output:

The video does not start, play/pause button also does not work.

Note:

Qt 6.8.5: This issue is not reproducible on macOS. When the subtitle track is changed, the video restarts.

Qt 6.10.0: When video is at the end and subtitle track is changed, the video restarts but the screen is black when the seek bar reaches 10 secs, the video is stuck for a second there and then resumes from there.
