Issue with PV 5.10 with the Python Shell and help()

I’m using the PV 5.10.0 installed version from the download site and when I try to use help() on anything I get the following:

Python 3.9.5 (default, Dec 22 2021, 22:21:42) 
[GCC 7.3.1 20180303 (Red Hat 7.3.1-5)] on linux
Type "help", "copyright", "credits" or "license" for more information.
Module readline not available.
>>> help(int)

I’m getting similar behavior for the PV 5.9 installed version but not PV 5.8 version.

Note that this is on a RHEL7 machine.

Andy,
I believe this is https://gitlab.kitware.com/paraview/paraview/-/issues/21000. Mathieu found it, and I just scheduled it.

As a work around, just call help again.
