Demonstration of this bug

Place a textarea inside a div. Give it height/width of 100px.

The enclosing div's height will be 104px. The textarea is taking up 4px extra
space below itself.

If you increase font-size, the phantom height also increases — 2em = 8px, 3em =
12px, etc.

(If font-size >= 6.969em — no jokes, that's the exact number I arrived at —
then you also start to get even MORE phantom height both below AND above the
textarea. Watch out for that in testing this bug!)

Problem first noticed while working on linked site — observe that there is
actually an extra 6px height below the div in this case, not 4px, indicating
there's even more strangeness at work here.

I can't figure it out. I leave it to smart people.

Demonstration attached.
