Aloha doesn't trigger the smartContentChange event when making formatting changes

If you toggle edit mode and click on, say, the title field, and change it, then click off, it pops up a warning that says you're about to lose your changes. This is good.

If you click into body text and make a word bold or whatever, however, and click off... you no longer get the warning, and you lose your changes. Same for links and other things you do through the toolbar.

Marking major since it's a data loss issue, but it's also a bit of an edge case so I'm not going to slot it in this sprint unless it's something easy.
