Ever since table sorting was introduced, HTMLTableCellElement was split
into two descendant interfaces, HTMLTableDataCellElement for <td>, and
HTMLTableHeaderCellElement for <th>. No browser ever implemented this
split. Although table sorting was removed in
59b7e24,
the split remained; we now remove it, fixing #1115.

Did table sorting introduce the split? It seems to me it was introduced earlier, to deal with the semantic differences.

I think we should say "only conforming" since they'll work either way. @zcorpan might want to take a look too.

LGTM with "only conforming"

I wasn't sure conforming was relevant to IDL attributes but works for me

I should probably check with history but my recollection is that it was introduced so that you could add table sorting-specific methods and attributes to <th> elements.

Nope, see 6db0d8d (modifies HTMLTableHeaderCellElement, doesn't introduce it).

7424da0 has something to do with it, but it seems it started before that and I can't find when.

Based on 2ac31bb and 7ccc7fc it has always been this way.

And it is better design, but it was just never implemented or cared for.

Merge the two table cell interfaces together
e383ae2 
Ever since the dawn of HTML (2ac31bb),
there have been two table cell interfaces, HTMLTableDataCellElement for
<td>, and HTMLTableHeaderCellElement for <th>. No browser ever
implemented this split, instead using the single HTMLTableCellElement
interface. This aligns the spec with browser reality.

Fixes #1115.
