 Twemoji replaces images that do not load with the original text, which is
 detected by our mutation observer that parses any added text nodes. If the
 image never loads there will be an infinite loop.

 To fix this we’ll have to look at the removed nodes in the mutation record
 and return if twemoji is replacing an image with the text in the alt
 attribute.
