That's the default.

Presumably this shouldn't make a difference.  If it does, we clearly
have a bug.

That's the default.

Nowadays, this shouldn't make a difference either, but it's a recent
change and may have bugs in that respect, indeed.

Not sure what that means.  But "C-SPC ..movement.. S-prior" will keep
the region active, but the region is delimited not by where you hit
C-SPC but by where you hit S-prior.  That's by design of
shift-select-mode.  Maybe CUA behaved differently in this respect and
since CUA nowadays uses shift-select-mode rather than rolling its own
this could explain the change.

If that doesn't explain what you see, then please provide a test case
(and make it a bug report).
