Provided the doctype of the page is some variant of xhtml, you will
see the same in e.g. Mozilla-based browsers because <option value="1"
selected> is invalid html. The correct form is <option value="1"
selected="selected">. It looks slightly nonsensical, but in xhtml,
attributes must be quoted, and may NOT be minimized [1]. The best fix
is to alter your extension's output so that it produces valid (x)html.
