Images not showing on CKEditor 5

This issue was produced by limiting the tags which can be used and for some reason the tags got changed when trying to add image via IMCE file manager.

Adding an image with CKEditor 5 built in Insert Image plugin and using IMCE works fine.

Closing this issue.

I ran into this problem too using IMCE Version: 3.0.9 with core CKEditor 5 and Drupal Version: 10.1.5.

There is a workaround if you still want to use the "Limit allowed HTML tags and correct faulty HTML" filter.

By default, CKEditor 5 uses these tags .
IMCE uses . So "data-caption" and "data-align" are missing.

You cannot manually edit the allowed HTML tags with CKEditor 5 (Filter settings tab - Limit allowed HTML tags and correct faulty HTML ). But you can add then to the Manually editable HTML tags under the Source editing tab. Just add "" to it.

Seems to work.
