Screenshot of relevant state

In the case I captured in the screenshot, it appears that window.dispatchEvent is midway through the call stack.
It has an invalid source location, triggering a console assert. We should be able to gracefully handle this case.

It would be even better if native/builtins have their own color in the call stack sidebar section, but that's another issue.
