@CrochetFeve0251 Thank you for the PR.

The issue has been fixed but there is a console error that's not there with trunk:

Uncaught TypeError: Cannot read properties of null (reading 'focus')

This can be seen here:

1. Click on the jellyfish picture.
2. Close the lightbox using the x button or the picture itself.
3. Check the console log.

Can you please check this? 🙏
