Similarly, using SetBold() or SetColor() has no effect.  But note that before initialization of my associated vtkContextView, SetColor(), SetBold() and SetFontSize() all work just fine.  The above code needs to run after initialization.  And again, it worked with no issues before.

I was just looking at this in ParaView, and it looks like a regression
has crept in. It may be the new label caching code not invalidating in
places where it should - leave it with me.
