Since the last update there is a problem with custom fields and JCE. The media class is missing (what unfortunatelly broke the whole site for me 🙁 )

Steps to reproduce:

1. Create Custom Field
2. Choose: JCE File Browser (media)
3. Set media type: image
4. Set media class: testclass
5. Got to the article, add the image in this customfield and take a look on the website.

In my frontend the image is shown correct but the class is missing.
Code:
<img src="https://www.joomlacontenteditor.net/images/demo/image.jpg" class="" width="" height="" loading="lazy" alt="">

Thank you Ryan! We found a temp bugfix and will wait for the new Version.
