Technically not a bug.

While it's not that convenient, the fact is that under the hood, all the different modes share the same bunch of settings. As a result, we kindof have to guess what to do in each case when switching modes. Current behaviour is based on the following assumptions:

  • Changing to Shapekey Editor, you do want to show the sliders, as that's one of the main reasons that editor exists - to facilitate easier animation of shapekeys, in which case you need to see the sliders to adjust the values + insert keyframes (since the properties listbox doesn't let you see all the channels)
  • Changing back to the Dopesheet Editor however, you cannot assume whether the user had the sliders enabled before or not. So, it seemed like a better idea to just leave them in place.
