    Description

      Steps to reproduce:

      1. Patch the mediaplayer example (to work around QTBUG-95397 and show another issue with position's change signal):

      2. Open https://bugreports.qt.io/secure/attachment/113067/bannerlord.mp4 from QTBUG-88693.
      3. It will start playing automatically; pause it.
      4. Seek to a position further back in the video. Notice that the position signal is also constantly emitted after doing so.
      5. Now press play to resume the video; it will start playing from where it was before you paused it, ignoring the position that was set by seeking.
