This would interfere in situations where a user has deliberately selected a set of tracks in the playlist to carry out a specific action, like modifying tags. Such a behaviour would be unpredictable and error-prone to the extent where I can imagine that people would eventually report it as a bug.
Hm, I did the following test. Selected some tracks in a playlist, openend the properties window, selected an unrelated item in the Facets view, right-clicked "Edit->Highlight in Playlist", then changed a tag field in the properties window and pressed OK.
The result was that the tag field was written to the initially selected tracks and not to the tracks highlighted from the Facets view. So I don't see a problem with that.
