Create a DOM element with $("<input />") adds unexpected content

[cFreed]

The $("<tag />") statement creates a normal DOM element like <tag></tag> for any tag value.

The $("<tag />").html("") statement should produce exactly the same. But in fact, when tag is INPUT I get (with jQuery 1.4.2) the following DOM element:

<input><input xmlns="​http://www.w3.org/1999/xhtml"></input>

It may be easily controlled in the console, using:

$("<tag />").html("").html()

which returns an empty string for any tag value, except INPUT.

It's not valid to try appending *anything* to a tag that cannot other elements, such as <input> or <br>. Since it's an error condition, the browser may not give the results you expect.

Sorry for the noise: sure it's obvious as soon as pointed!
