Captions not working in Drupal 10

Can you please add specific steps to reproduce the issue? Thank you.

Thanks for getting back. Here's a quick example: Like I said, it would be nice if captions displayed on the derivative, too. Thanks!

Hi @bcobin,
Can you please give me the specific steps to replicate this issue on a brand-new Drupal 10 installation? For example:
- Step 1: install Drupal 10.
- Step 2: install colorbox.
- Steps 3-N: each incremental step until the issue is reproduced.

I need to reproduce the problem myself, in a local environment, so I can clearly verify whether a proposed patch actually fixes the issue.

Thank you.
