short test summary info - empty cause sometimes

For some types of errors there doesn't seem to be a cause printed to terminal:

================================================================================================================================================== short test summary info ==================================================================================================================================================
FAILED xyz_test.py::TestXyzSuite::test_xyz[xyz]

Where normally there would be some description printed after that.

Trying to follow the code I end up in:
https://github.com/pytest-dev/pytest/blob/baada535a3e31ceb541a3e81319309a35bec934c/src/_pytest/terminal.py#L1310
which do:

        try:
             # Type ignored intentionally -- possible AttributeError expected.
             msg = rep.longrepr.reprcrash.message  # type: ignore[union-attr]
         except AttributeError:
             pass

I suspect the "pass" line above is when I don't get a cause printed?

Here I wonder why not call longrepr._getreprcrash() instead? From:
https://github.com/pytest-dev/pytest/blob/69f2855cc8896c67c499a250c2f08fcfd408f827/src/_pytest/_code/code.py#L605

And perhaps put the lines above in there instead?

Start in src/_pytest/terminal.py around the short test summary handling and compare it with _getreprcrash() in src/_pytest/_code/code.py. Reproduce an error whose short summary has no cause, then trace the longrepr representation path. Done means the summary includes the expected cause without breaking errors that lack a reprcrash message.
