Thanks Alvin - so I guess it could be defined as a bug, depending on what one's definition of bug is.
The reason why this is a problem for me and maybe others - sometimes I create a few dozen views in model space, then I create a viewport in paperspace. Sometimes I want to go back to a particular view in modelspace - so I look at paperspace to see what the view is, and sometimes I can not do that if the view name is missing from the properties window of that view, so I have to scroll through all the view names in model space to find it.
It's kind of an annoyance.
Two workaround suggestions:
1) Use Floating Modelspace
in Paperspace [Model Space (Floating)
]. If doing so-- and intending to do some zooming in or out and/or moving the Camera around while working-- you might want to Lock
the Scale and Camera in the Viewport/Viewport page first.
2) In the Viewport, in the Viewport->Properties->Camera page, take a screen-capture of that page, using Windows Snipping Tool or something. Then, back in Modelspace, enter all the same Camera values (Position; Target Point; Up) in the Camera Properties.
Tedious... I know. That's why they're called "workarounds".
