Started a new forum post, input some content... after X seconds autosave saved a draft.
User decide to cancel the forum post, click "Cancel" button.
Now, the user is returned to main forum page and click the "Add new discussion" button to start a new forum post, BUT the old draft is presented inside the editor. (Title is correctly cleared)
Expected behaviour: clicking the "Cancel" button should clear the auto saved draft content.
In other words: clicking the "Cancel" button on a Moodle form should clear all ATTO instances auto save draft content.
