Describe the bug

Ad an admin, when I set the max length of a proposal's comment to 1500, and then I post a comment which length is superior to the default value (1000 chars) but inferior to the max value, it is then not possible to edit this comment.

To Reproduce

1. Log in as admin and access Back-Office
2. Go to a participatory process, and access to the proposal component of it
3. Modify the component to fix a limit of characters for comments superior to 1000 chars (= default value)
4. Access Front-Office of this component
5. Access a proposal and submit a comment over 1000 chars but below your limit
6. Try to edit it and stay over the 1000 chars limit
7. See that you have an error message

Expected behavior

When I set a max length for a proposal's comment superior to 1000, and I post a comment with a length superior to 1000, I expect to be able to edit it.
