Duplicate artists returned from UPnP search

[simbun]

Hi Simon,

I'm sure it's been like this forever, but I've just noticed that if I apply a sort order to the albumartist tag then my search results include the sorted version of albumartist and the unsorted version of the track artist.

Code:

itemTags:AlbumArtistSort
tagValue: AlbumArtist.value.sort.index={AlbumArtistSort}

Search results:

Code:

Elton John (track artist results)
John, Elton (album artist results)

I appreciate that I can fix this by adding a sort to the artist tag (even though I don't use the All Artists index), but shouldn't search return the display (non-sort/index) value anyway?
