Adding an event handler in an event handler can lead to infinite looping

Not sure what the implications would be, but a solution might be as simple as using the "initial" length of the listeners array in the loop condition (instead of using the "current" length) for ShadowDOM/src/wrappers/events.js' invoke() method:

Yeah. Native does not add the functions to the current listeners. I'll update.
