Unsaved changes are lost when you get back to edit the comment

Summary

When you are editing a comment of an issue if you leave the issue page, get back to it, then try to edit the comment by just saving it, the editions unsaved are lost. This happens on the new issue view.

Steps to Reproduce

1. Click to edit a comment on a ticket;
2. Leave the page (without save or cancel the edition);
3. Get back to the issue;
4. Click to edit the comment where the comments weren't saved;
5. Click to save the comment.

Expected Results

The unsaved changes will be saved and shown on the comment

Actual Results

The unsaved changes are lost, even if you try to edit the comment again

Notes

Workaround

If you add a small change to the unsaved changes of the comment (space or a point) the editions aren't lost when the comment is saved.
