[Bug 22914] Unclear if setting element.dataset.fooBar should update data-foo-bar attribute

https://www.w3.org/Bugs/Public/show_bug.cgi?id=22914

--- Comment #3 from David Karger <karger@mit.edu> ---
Good; thanks for pointing that out.
I was investigating because jquery's .data() method, which seems awfully close
to implementing the html5 spec, does *not* perform this reflection: it
explicitly states that the .data() object is populated only once, and any
future modifications to the object or to the DOM do not reflect.
