Attempted Patch

Development provided a patched library, however, it did not have any positive impact on the problem. Instead, the browser then reported the following:

TypeError: cannot read property 'getEditor' of undefined(...)

In the end, we had to get the customer to roll back their instance. This bug is being raised to determine if this is a bonafide bug, or a freak occurrence.
