test to drop into editing/editable-region

If an element is clipped with the clip-path property, event regions need to respect that; currently, editable regions (which do not rely on clip-path being composited) are wrong for descendants of elements with clip-path.

This is important because content uses clip-path to hide descendants from hit-testing (see bug 214362).
