Add HTML content: while HTML content is not saved buttons stop working after opening preview #1518
Description
Open any page/blog -> add new content -> choose HTML -> enter content name, content and press Preview: preview will be opened ok. Close preview and click on Preview button once more in Add content modal: now preview won't be opened. Try to save content by pressing any save button - content won't be saved (no errors in console; tested with Chrome/Firefox)
Issue is valid just in new HTML adding modal, other types/edit mode previews works ok
