The File.webkitRelativePath of the File interface previously returned a value different from other major browsers, now it returns the same value. For example, if a user has the following local files: /tmp/a/foo/bar/1.txt, /tmp/a/foo/2.txt and they selected /tmp with a file chooser dialog, webkitRelativePath in Chrome was: foo/bar/1.txt, foo/2.txt Other browsers, which Chrome now matches, return this: tmp/a/foo/bar/1.txt, tmp/a/foo/2.txt
