It is hard to investigate without a reproduction 😞
Do you at least know which browsers are affected. (Could it be that this only happens on IE?)

• The error seems to happen on this line, when $$scope.$root is null.
• This happens when $$scope has been destroyed.
• AFAICT, for the error to appear, $setViewValue() has to be called asynchronously and scope be destroyed between scheduling $setViewValue() and actually invoking it.
• This can (only?) happen if the input listener is called asynchronously, which happens on browsers that do not support the input event (i.e. IE).

It sounds reasonable to add a check for $$scope.$$destroyed in $setViewValue() or $$debounceViewValueCommit(). But without a way to reproduce the issue, we can't be sure if it is actually fixing anything 😁
