Webkit: Radio checked state incorrect when creating an input with a name

[sirshannon]

In Chrome and Safari, I'm getting an error creating a radio with a checked state:

$('<input type="radio" checked=""/>')[0].checked returns true

$('<input type="radio" checked="" name="foo"/>')[0].checked returns false

Both of the above examples properly return true in FF and IE.

The checked attribute should be set to the value "checked" in the markup; setting it to an empty string isn't consistent across doctypes. When the value is set via jQuery you should use a boolean, e.g., .attr("checked", true).

Regardless of what the doctypes say about the attribute, I would expect the behavior to be consistent in both cases. Whether or not 'checked=""' is valid doesn't change the fact that the first example works, but the second example doesn't. This is a bug.

I just ran your original test case in Chrome and Safari and was able to get the exact same output experienced in FireFox and IE.
