causing a pause in typing

 Please note that this does NOT apply when editing menus from Appearance ->
 Menus.

 Steps:

 1. Edit a menu item's navigation label or title within customizer
 2. Try to type a long sentence

 Frustration results from:

 1. While trying to type the preview pane refreshes multiple times
 resulting in pauses during typing.

 Ideas to fix:

 - Increase the amount of time between preview refreshes when typing
 - Wait for a pause in typing of a certain length (I think this might head
 into accessibility territory so I'm not going to suggest a wait-time)
 - (I don't like this one but here it is): Only refresh the preview pane on
 unfocus event

 I marked as performance as well because this causes a LOT of refreshes
 which may or may not affect server load.
