Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[Erik Arvidsson]

tr elements have the wrong prototype/constructor


var tr = document.createElement('tr');

assert(tr instanceof HTMLTableDataCellElement);
assert(tr.constructor === HTMLTableDataCellElement);
assert(Object.getPrototypeOf(tr) === HTMLTableDataCellElement.prototype);

IE gets this right

Sorry. "td"

var td = document.createElement('td');

assert(td instanceof HTMLTableDataCellElement);
assert(td.constructor === HTMLTableDataCellElement);
assert(Object.getPrototypeOf(td) === HTMLTableDataCellElement.prototype);

Okay... So HTML split this up to only add .abbr to <th> but then .abbr is still on <td> via the "obsolete" section meaning we still have .abbr on both <td> and <th> but now for each it's on their own descendent interface. Not sure if this is an improvement...

Yeah, I think this is bogus.  There's no reason I can think of for this split and the ensuing compat-breakage....

Left to my own devices, I'd wontfix this and file a bug on hixie here.  Peter?
