Does anyone else think it's at least a little bit creepy that a tap fires a mouseover event? I mean, hmm a click doesn't, so why does a tap? How does a tap firing a mouseover event in anyway aid accessibility? I might be missing something, but I just don't get how this is ever a good thing. Or if it is, how it's a good thing more often than it's a bad thing. My point being that IF it's ever good, most of the time it's bad, and I can't even imagine a case where it's good, can you?
I think they just threw it in because they didn't think things through.
