Summary0002595: form submit with <button> does not send its name/value in form POST
DescriptionThis works:

<form method="post">
    <input type="submit" name="button" value="Button">

This does not:

<form method="post">
    <button name="button" value="Button">Button</button>

According to HTML 4 (as far as I understand it) requires also <button> to send its name/value on form submit: https://www.w3.org/TR/html401/interact/forms.html#h-17.5

See "URL of problem page" for a link to an example.
Steps To Reproduce- create a HTML form with button
- submit it
- name/value not available as "POST parameters" on server
