Steps to reproduce:
Serve attached HTML file with a web server, then open it in Safari on iOS 9.3.2. Observe that TypeError is thrown.

Calling the custom method should have worked.
Actual outcome:
Test fails with TypeError, undefined, in Safari on iOS 9.3.2, works in the other two browsers tested.</pre>
