Please add the following two test cases for cloning a textarea with non-initial
value:

* User input
var textarea2 = ...;
textarea2.focus();
document.execCommand('InsertText', false, 'foo');
document.body.appendChild(textarea2.cloneNode(true));

* Updating IDL value
var textarea3 = ...;
textarea3.value = "foobar";
document.body.appendChild(textarea3.cloneNode(true));

I have updated the patch with added test case.
In this test I had observed another rendering issue which may cause this ref
test to fail.
Bascially spacing issue between textareas is not preserved when we do append of
textarea element on body.

I assume to keep this ref test as fail and file new bug to fix that rendering
issue.
