8874	Shift+tab causes errors and incorrect caret and focus movements	Piotrek Koszuliński	Garry Yao	"1. Open replacebyclass.html sample
2. Place cursor somewhere in the paragraph
3. Press Shift+tab

* On Chrome there's an error on console and caret moves to the beginning of the editable.
* On Firefox there's an error and focus is lost.
* Opera ignores shift and moves focus to submit button.
* On IE8 editor loses focus.

Some of these incorrect behaviors (IE8 & Opera) are old, but error on Chrome&Fx is introduced by r7372, so it's a regression from 3.6.2.
