SUMMARY
Media player widget on system tray displays incorrect song details when switching between songs in a YouTube playlist.

STEPS TO REPRODUCE
1. Play a mix or any playlist on YouTube.
2. Open the media player widget on the system tray.
3. Allow the first song to play for a few minutes.
4. Skip to the next song in the playlist.
5. Observe the details (such as duration of song, current time) in the media player applet.
6. Go back to the previous song in the playlist.
7. Observe the details (such as duration of song, current seek position) in the media player applet.

OBSERVED RESULT
1. The details (such as the length of track and current seek position) appear incorrect when switching back to the previous song.
2. Observed for Firefox and Chromium.

EXPECTED RESULT
The media player widget should display the correct details (length of track and current seek position) for the song being played, regardless of whether it is the first or previous song in the playlist.

I'm not able to reproduce this on Plasma 6.4.5, so this may have been fixed. I switched back and forth between multiple songs in a YouTube playlist, and the media player widget track details always matched what was shown in YouTube.

Could you attach a screen recording of this, so I know I'm performing the same exact steps in the same way? Thanks.

I recorded the screen while trying to recreate the issue and it took me more tries than I thought, so the video got a little longer than I would've liked (also the first 2 entries in the mix had same duration). The video is of 12MB, whereas attachments can be max 4MB. I am sharing the link to the video here: https://streamable.com/w45143 . It will likely expire after some time.

I do not own any songs in the video and just played them as YouTube presented them.

Thanks for the video. I do see the problem show up around 00:52, where the song is shown by YouTube to be 0:06/3:07, but the Media Player widget shows 0:18/-3:26 (which corresponds to the song that had been played before it (2 positions previous in the playlist)
The problem happens again, I see, on the next song as well
It looks like I had been doing the same things, and I tested again based on what you did in the video to be sure.

I recommend running updates on your system, since it's behind. Fedora 42 should have
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2

If the bug still happens after the system updates, see if you can reproduce with a brand new user. Thanks!

Same issue as Bug 507597: the website sends us junk data.
