bug#53150: 29.0.50; Behaviour change in master branch

[Ergus via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hi:

I have noticed a change in the current master I am not sure it is
intended or an issue.

On emacs 27 when the region is active and I press C-x C-x to go to the
other end, then I can use move commands (arrows) to change the region
boundaries (extend or reduce the region).

Now on master if I do the same after C-x C-x if I move the cursor, the
region is automatically deactivated immediately.

To reproduce:

emacs -Q
C-r te <RET>
C-SPC
M-f M-f
C-x C-x
M-b (or C-b, C-f etc) ;; this deactivates the mark unlike emacs 27

Is this intended??

Best,
Ergus

I can't reproduce this on the emacs-28 branch.

I don't think so, no.  A git bisect would be welcome.

Crystal ball says it's 19c6cad182, so Ergus might want to try just
reverting that before carrying out an entire bisect.

Thanks.

I hope I fixed this now.

Andrey, could you please verify that bug#52896 is still fixed with the
current master?

This bug was left open, so I'm closing it now.
