Add assertions against stray classes

Browse Source 
In previous iterations of the classPersister, we
found issues with the implementation meant classes
it should have added back to elements were also
added to other elements. This adds tests for this
scenario to ensure it doesn't happen again.

Also includes changes to fix a linting error with
the JS which complained about a function being
defined in a loop while referencing variables in
the outer scope.
