[docs] Clarify that MutableData must be applied to tree between change and usage #4914
Description
Description
The Polymer.MutableData mixin allows for an assignment or notification of an object to cause all side-effects of the object and all of its child objects to be re-evaluated by skipping dirty checking for all objects.
The API documentation should clarify that all elements in the binding tree between the source of the change and the consumption of the change must also mix in the Polymer.MutableData mixin (or set the mutable-data attribute on elements that use Polymer.OptionalMutableData like dom-repeat).
