Audio Source Synchronization - Marker Issues

Hi! I know there have been a lot of issues about loss of proper synchronization with audio sources lately, including loss of markers and inability to create them. It has impacted most of my synchronized scores as well.

It appears that some progress has been made fixing this in the last couple of days, but it's still not working properly, and I just want to be sure the Musescore is still working on a full resolution. Here is what I'm seeing/hearing now:

1. I go into an audio source. I am able to add and insert markers as usual within the audio source editor. It appears to play back fine within the editor. The measures track the sound perfectly. I save the work.

2. I return to the score and do a test playback. Now the highlighted measure is some distance ahead of where it is actually playing. The distance ahead depends on the amount of "silence" at the beginning of the audio source. My best guess is that an extra marker has been placed at point zero in the audio source file.

3. I go back to the audio source to check, and all the markers have disappeared. I start over at Step 1, and the same thing happens again.

Thanks for any help you can provide!
