When editing a page with form controls, you should be able to click on them to select them (they draw with a blue outline), then delete them. This does not work for <button> elements.
The fixes here are: 1. Change nsHTMLButtonElement's event handling to ignore events if the control has user-input style. 2. Add 'button' to the list of control elements in EditorOverride.css r=/sr= please.
