Sorry about that and thanks for the pointer.

The problem is that I want to show the spinner page only when the page
loading takes long time (not by default), as HIG suggests:
https://developer.gnome.org/hig/stable/progress-spinners.html.en

So,

the nested stack / overlay approaches sound the best fit for my
use-case.  Perhaps there could be a specialized widget which supports
this pattern, if the use-case is common?
