Reproduction steps:

1) Setup a vanilla bundle with CKEditor
2) Start the server, login as admin
3) Go to: Product Menu -> Test Site -> Content -> Web Content -> ellipsis menu -> Structures -> '+' button --> Create new structure
4) Add a text field with the attribute => repeatable = yes
5) Within the text field, add an HTML box (doesn't need to be repeatable)
6) Create a new Web Content from the newly created structure
7) Write some text to the first html box (CKEditor)
8) Add a second html box via the '+' Button => write some text to it
9) Reorganize the text blocks with drag & drop

Expected behavior: The ability to reorganize the boxes, no loss of the text entered into them
Actual behavior: It will be possible to reorganize the boxes, but the text entered in the HTML fields will disappear
