"Invoke the Function. Use the third and subseque..."

https://html.spec.whatwg.org/#timers:es-invoking-callback-functions

Invoke the Function. Use the third and subsequent method arguments (if any) as the arguments for invoking the Function. Use method context proxy as the callback this value.

I believe this is missing exception handling. What happens if a timer callback is a function and that function throws an exception?

Hmm yeah, that should probably invoke "report the exception" with the exception. It's really surprising this hasn't been noticed until now though. Makes me wonder whether I'm missing something.

I think the plan was to clean this up as part of #958, but a quick patch would not be a bad idea in the meantime.

This has since become more correct:

If handler is a Function, then invoke handler given arguments with the callback this value set to thisArg. If this throws an exception, catch it, and report the exception.
