Can you please try with lvm2-2.03.09-5.el8? It looks like the changes that caused this behaviour changes were reverted, see bug 1868169.

Indeed I'm not able to reproduce the issue with lvm2-2.03.09-5.el8.

It works well with lvm2-2.03.09-5.el8. Thanks, pino.

Thanks for noticing it in the first place, and for testing again.

Closing the bug, then.
