[B-18402]Hide Selected Tracks does nothing in top split-view

Cubase 8.5.20 on Mac OS X 10.11.6

  1. Create a new project and add a track of any type
  2. Enable “Divide Track List” for the project window (so tracks are divided into a top and bottom area)
  3. Make sure the track you created is in the top half of the project window (if it’s not, drag it up there)
  4. Right-click the track and select “Hide Selected Tracks”. Nothing happens.
  5. Drag the track to the bottom half, and repeat step 4. This time it works.

Confirmed on Windows as well. As a work-around, hiding tracks using the Visibility works as expected.
Reported, ref. number [BON-18402].

Thank you.
