I don't read the spec that way.  The phrase "with the bottom of the element
aligned with the bottom of the viewport" seems to rule out the possibility
of other alignments such as suggested above.

If you wish browser vendors to have the freedom to experiment here, perhaps
a vague sentence such as "the user agent should scroll the element as
necessary such that as much of it as possible is visible in the viewport"
would suffice.

My impression was that Firefox 3 changed scrollIntoView behavior precisely
to comply with the detailed description currently in the spec.

It is effectively optional now. Horizontal scrolling is also required.


Now I'm wondering whether I'm looking at the wrong version of the spec,
since I don't see any of that.
http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#scrollintoviewstill
seems to read a lot like I remember it...
