After Upgrade 7.11.8 to 7.11.9 case description isn't stored anymore

I searched the forum and found this topic:

https://suitecrm.com/suitecrm/forum/suitecrm-7-0-discussion/18759-case-description-field-text-entry-isn-t-saved-after-upgrading-to-7-10-4

same behaviour like described in the ticket.

I did a rollback to 7.11.8 - using the same machine, same browser etc. and it worked well.

Is there any workaround for this issue in 7.11.9?

Hi
Check out these two files and try to put the given code in
