I dealt with this in bug 214179, but it turns out my implementation was flawed. It's possible for a descendent layer to contain a point that its ancestor doesn't, and this occurs very commonly with iframes (but not at all commonly with overflow scrolling). The Mac backend deals with this by just not doing any bounds checking, so we should do the same with nicosia.
