Make blocking pointer-events optional

In my application I want to get both the color and mouse coordinate of that color, but the eye dropper seems to block pointer events. I understand you might not want to extend EyeDropper to include more features, but I can't add these features myself if exists outside other events.

This likely has privacy reasons. I don't think it actually makes sense. Worst thing I could imagine is knowing on which buttons someone clicks in an iframe, but from my understanding that is an issue already. The blur event is being triggered when clicking on an iframe and with window.active() one can indefinitely track mouse clicks on iframes. So if it is a privacy concern, I'd be very interested in hearing the reason.
