If I copy from
https://www.mediawiki.org/w/index.php?title=Wikimedia_Engineering/2013-14_Goals&veaction=edit
to https://www.mediawiki.org/w/index.php?title=User:Eloquence/CP_tests&veaction=edit after clearing it
and select the first section (from start to "new opportunities." including the navigation template), I get a JavaScript error
Uncaught TypeError: Cannot call method 'getType' of undefined
on the console, and VisualEditor becomes unresponsive.
Version: unspecified
Severity: normal
