Mosaico editor failing to load completely
When re-using a past email or attempting to create a new email using Mosaico, the editor appears to not load completely. In addition to the template thumbnail displaying as missing, when clicking the "edit" link the screen begins to load with the correspondending "loading" message in the top-right, however it does not proceed beyond that. Likewise, actions such as save, delete, esc, during this "loading" are unresponsive.
