Comment:

 Think I got to the bottom of it :)

 Happens when we try to "close" the second row of toolbar buttons on
 initializing the editor. It looks at `editor.iframeElement.clientHeight`
 which, as the whole iframe is in a hidden div, is 0/not set. Then we
 increase it with 30px to compensate for the closed toolbar row. That's why
 the iframe height gets set to 30px but the textarea (where TinyMCE takes
 the height from) is still correctly set to 300px.

 It's a small but annoying regression. Patch coming up.
