Steps to reproduce:

• Create an article
• Add and save a tweet (could also be any other Custom Tag) into the article text.
• Click on the cog of the tweet element. The attribute preview is shown.

Result:

• The attribute preview is not directly closable (see screenshot ). The only way to get rid of it is to open the attribute editor via the edit icon in the attribute preview.

Expected:

• Attribute preview should be closable without entering the edit form.
