Strange behaviour with text fields in the customer CMS

Since the update to the new design of the Website Builder, we have had a very strange problem several times:

When the client edits a text field, it can happen that a strange HTML code is subsequently inserted into the text field. The result of this code is that the whole text field is treated as a link and the links in the text field no longer react.

The HTML code that is added looks like this (the first to div tags):

This problem must have arisen with the update of the Website Builder. Because we never had this problem before. Since this change, we have had this problem. Approximately five customers have reported this problem.

The problem can only be solved by removing the wrong div tags in the HTML editor. It has also happened that the exact same text field has shown the same error again when edited later.

While I was writing this message, a customer had this problem again! I ask you to look into this matter urgently!

Hey @Patrick_Luescher could you name me some website IDs for us to check?

Thank you, André!
I will send you an email.
