 Please notice that this patch, using message._messageName, will work on
 NoScript 10.1.9.6rc3 (or 10.1.9.6 stable) and above, which gracefully
 handles "legacy" message recipient by adding this property for them:
 https://github.com/hackademix/noscript/commit/71c82b50849d8d70bb5bc410fcdf814837358143.

 Currently all the message metadata, also the name, is meant to be confined
 in a ```__meta``` (notice the double underscore) object, which always
 includes a "name" property, like


 {{{
 message.__meta = {
   name: "start",
   recipientInfo: {},
   //... possibly other properties in future
 }
 }}}
