* Change the behavior of the `font-size` selector, to not use `styleWithCSS`, and generate a `<font>` tag. This is required so that we can have consistent behavior between browsers - Firefox does not respect the `styleWithCSS` flag on `fontSize` and was generating `<font>` tags anyway. https://bugzilla.mozilla.org/show_bug.cgi?id=1022904

* Remove `font-family` auto selection when showing the toolbar, because it was causing issues with the new `font-size` behavior - since we now have multiple editor toolbars the last selection will still stay active.
