Positioning Z-Wave roller shutters with Z-Wave JS

I have several Fibaro roller shutters (aka blinds). With the Z-Wave JS integration, it’s possible to shut them and stop halfway down (or up, if you are opening them). However, when you press the Stop button, it’s not possible to further close or open the blinds at that point (button is greyed out). Only the other direction is available.

How to reproduce:

  1. Blinds are open
  2. Press Down Arrow to close
  3. Press Stop halfway
  4. Result: Down Arrow is greyed out. To further close, Up Arrow must be pressed, then Stop and the Down Arrow again

Is this intended functionality or a technical limitation? Or can it be configured/changed in future releases?
