Description

Very useful project!

I find that when running tests with jasmine-maven-plugin, specifically when running a headless test (which internally uses HtmlUnit for the "browser") that event.relatedTarget can be null. This throws on line 118 which tries to get event.relatedTarget.ownerDocument. The same thing works fine when testing inside a browser.

My fix is:
eventDoc = event.relatedTarget ? event.relatedTarget.ownerDocument : undefined || document;

Research direction

Start at line 118 in the event-handling code and reproduce the issue with a headless test using jasmine-maven-plugin and HtmlUnit. Verify that a null event.relatedTarget no longer throws, while browser-based event handling continues to work as described.
