I've just migrated our dev site from v6.2.5 to v7.2.8 and noticed that the "Styles" dropdown has changed to "Formats" which I can live with but on v6 if I changed the style of some text to a header (only have h1, h2, and h3 as the options) I could highlight the text again then choose "Styles" in the dropdown and it would remove the style.

Selecting "Formats" in v7 doesn't remove the formatting so how do I get this to work as it did in v6?
