-Have an XRNS expanded in the discop to browse internal samples
-Save that song with one of the samples still selected
This causes the XRNS to collapse which makes sense as sample data may change. However the selected song may now change: If you were browsing a sample 3 slots down, the selection becomes the song 3 slots down.
You would expect the selection to default to the song you were browsing (just as when you collapse the XRNS manually)
