<select> tag required to be inside <form>

It looks like lynx (tested with 2.9.2) requires <select> to be inside
<form>. If <select> is used outside <form>, lynx complains about bad
HTML. I suspect this is not the intended behavior. From the information
on the web, for instance

  https://www.w3schools.com/tags/tag_select.asp

it seems that such requirement does not apply in recent versions of
HTML. I tested it also with

  https://validator.w3.org/

where standalone <select> throws an error only for HTML 2.0, from HTML
3.2 onward it passes.

Best regards,
