MusicBee v3.3.7003.18853: bug when using Multiple tab search

[gdm]

When updating multi artist compilations,
I have the habit of searching a compilation and opening one fo the albums in one tab
and then using a second tab to search all music by an artist.

When "zooming in" on a certain album, and using search on the other tab, there is a minor issue that to zoom back out to the
compilations I had to reenter the search (or add / delete a blank)

But today the album track list was a number of blank lines and this resulted in following bug, with request to report:
