[Paraview] Pipeline not respecting the arrow of time after changing the inputs of a filter

[Utkarsh Ayachit]

Jonathan,

We can always use the paraview issue tracker to request new features,
including UI cleanups and redesign proposals.

https://gitlab.kitware.com/paraview/paraview/issues

It's generally a good idea to bring it to everyone's attention on the
mailing list too.
