Comment (by westonruter):

 @afercia thanks, please give [attachment:38667.2.diff] a try.

 * Adds Esc text to section contextual help.
 * Removes IE8-specific code.
 * Ensures that hitting Tab enters a Tab character after blurring the first
 time.
 * Moves `placeholder` for control to `default` value for setting.
