reset view options using key 'r' not working

I have implemented the volume slicer code, exactly as exampled in the documentation page.

When visualizing my scenes, everything works fine. I press 'f' and I am able to set the focal point and other keyboard shortcuts work aswell.

But the 'r' shortcut, which is the most important to me, does not work.

If you'd like to give it a try, just copy the volume slicer code (not the advanced volume slicer) and try it yourself.

Start by reproducing the issue with the documented volume slicer example, not the advanced volume slicer, and trace the handling of the 'r' keyboard shortcut. Done means pressing 'r' resets the view options while the other shortcuts, including 'f', continue to work.
