Truncate not working with pgAdmin 4 v6.3

I've noticed that Truncate no longer works with 4.6.3. (You click "Truncate" and nothing happens)

I've done a clean install, and had to revert back to 4.6.2.  I enabled debug logging, and no entries are made when clicking truncate.

Is this a known issue?  Or what can I do to provide more information to help troubleshoot?

Thanks,
David
