[Rwp] Is This a Bug: New Items Inserted On Last Track when no Tracks are Selected

[Matej Golian]

Hi there,
For testing I inserted 4 tracks into an empty project and than enabled
the master track. After that I navigated to the master track with the
up arrow and therefore assumed that only the master track was
selected. But when I tried to insert some new items (as if on the
master track) just to see what happens, I found out that the items got
inserted on the last track eventhough no tracks were / were supposed
to be  selected.
According to my understanding nothing should have happened, but
apparently I was wrong.
First I thought that this had something to do with the new Osara
navigation / master track functionality, but now I believe that Reaper
is to blame here.
Does anyone know anything about this? Is this a Reaper bug or is this
perhaps default behavior?
