Mechanism to apply styling to the Formatting menu of QEditor

[dsl101]

We have some custom CSS that changes the default display of heading tags amongst other things, but the Formatting dropdown of QEditor is completely outside the scope of that CSS, and so the h1–h6 tags look completely different.

I couldn't see an easy way to apply the main page styling to this QMenu.

Perhaps a way of applying a class to the toolbar dropdowns? Or a unique class / id on that menu so that we can target it with specific CSS?
