1. What were you trying to do that didn't work?

Attempting to auto-complete nested commands by pressing TAB with bash-completion installed in RHEL 8 and in RHEL 9.

2. Please provide the package NVR for which bug is seen:

bash-completion (all RHEL 8 and 9 versions, to the best of my knowledge)

3. How reproducible:

Always reproducible.

4. Steps to reproduce

   4.1. Begin typing a command with a nested command, like so:

        # less $(which subscription-

   4.2. Hit TAB to try to auto-complete            

5. Expected results

The nested command should auto-complete. Using the above example, we would expect the following:

        # less $(which subscription-manager

6. Actual results

Nothing happens. In RHEL 7, this works as expected.
