Interface oddness in Artist Splitter

[Phaedrus]

Working through fixing my tags because my previous Music Manager mangled them for me. Found a bunch of multiple artists that are listed with "/" separating the artists. Not enough consistency in the artists to make automation reliable. Anyway;

In the "Artist Splitter," after splitting the artist, and editing the "display artist," hitting "Enter" does not save the changes to the "display artist" field. It does save the split artists, though. If I "tab" away from the artist field after editing, it works as expected.

Here's my process;
1. Auto Playlist to find candidates
2. Sort by artist
3. Select identical artists
4. Edit properties
5. Click the three dots next to the artist
6. Click the "Split" button
7. Adjust the split artists as needed
8. Edit the "Display Artist"
9. Hit Enter.
