RE: [css3-regions] How should elementFromPoint interact with Regions?

Our implementation doesn’t flow the iframe element, it flows its content (that option is currently not in regions spec, we are looking for better syntax, but it is what IE supports).

Returning iframe doesn’t make any sense, it is not used in layout at all. Returning an element in content or the region should be the two options to choose from…

We therefore suggest that if elementFromPoint(x,y) is called from a parent document and hits an element in a child document (e.g. displayed in a frame or region), an appropriate element from the parent document should be returned.  If the document is being displayed via an iframe or frame element, return that element.  If the document is being displayed via a region, return the region displaying the document.

IMHO you should always return the <iframe> element whether or not it's flowing into a region. What is the argument for returning a region element? I don't think you would ever return a region element for same-document content flowing into the region (except perhaps where the region has no content), so I don't see why you would want to for <iframe> content.
