Partially broken as of 4.9.4

The snippet overlay doesn’t open due to some Javascript error, but the wrapping button in post editor still works fine.

UPD: a version with the snippet overlay fixed can be found here Would be glad to integrate the changes into the plugin, but can’t find any contact of the author.
