So.. this issue has been killing me for a while. I imagine others are having this too, so I am going to post quite a bit of info here.
The issue is pretty basic. When I have an album open in iTunes I can double click a song to play it. All goes well, but when I click the heart next to the song (to remove or add a favorite) the album view will collapse and then I will be scrolled to the top of the albums view window.
This issue persists between operating systems, too. For example if I favorite a song in iTunes on a Windows machine, the same behavior occurs (although the album view isn't collapsed in Windows for some reason).
Here is the bug in action documented via GIF image:
I have a feeling this is specific to my user account, so here is some history that may be helpful.
I subscribed to iTunes match before Apple Music was here. I cancelled my iTunes match account before Apple Music came out.
I am now an Apple Music subscriber and I have a mix of Apple Music and purchased content. Favoriting a song from either source causes the issue.
