Cannot create `Opacity` or `Visibility` animations after loading state.
Steps to reproduce:
- Start ParaView, create
Sphere
,Apply
. - Save state as
sphere.pvsm
. - From
Animation View
create a new animation track for Sphere:Opacity. HitPlay
using the VCR controls. <--- this should work as expected; you'll see the sphere go from opacity 0 to 1. - Restart ParaView and load
sphere.pvsm
. - Now try to create a animation (similar to Step 3). <--- you won't be able to add a track for Opacity; this is a bug!
