Confirming that I was having this issue:
- Version 2.1.2 of MaxLength module.
- After upgrading to CKE5, the remaining character count was not updating on Paragraph content fields with the max length set (it was working in CKE4 on for those fields).
- I updated to MaxLength 3.0.0-beta1 and the issue appears to be resolved.
DMRupp β created an issue.
I removed "Needs issue summary update" because I added the detail that the inline forms error module must be enabled to recreate this issue. This is still occuring on core 9.5.9.
