I'm surprised Chrome returns a Unix path; is this on Windows?

The original plan was to just have the filename. Unfortunately, it turns
out that if you do that, there are certain sites that break, because they
expect the path (and they expect a Windows path, no less). This is why
Opera and IE8 return a fake path -- not because HTML5 says to do it. In
fact I made HTML5 say it because they were doing it.
(I would expect Firefox, Safari, and Chrome to follow suit; Firefox for
compatibility, and Safari and Chrome for privacy.)

I agree. Unfortunately, sometimes we are unable to make choices that end
up with a nice language. :-(
