Public bug reported:

When I'm on MySQL 8, I get a JavaScript console error when trying to add
an image to a group dashboard. This doesn't happen in Postgres.

The error is:

Uncaught Error: Invalid `previewsContainer` option provided. Please provide a CSS selector or a plain HTML element.

To replicate:

1. Mahara main with MySQL 8
2. Set up a group and edit the group homepage.
3. Add an 'Image' block and upload an image into the group files area.
4. Try to save the page -> it keeps spinning and the console shows the above error message.
