Subject: 26.3; EWW does not show textarea content
Date: Mon, 2 Mar 2020 23:25:45 +0800

I notice EWW doesn't show the textarea element's contents, for example,
save the following to a.html

    <textarea>HELLO</textarea>

then 'M-x eww-open-file a.html' shows some empty lines without any text.

The following patch fixes the issue for me. And the old code seems
assuming <textarea value='HELLO'></textarea>, which is not correct.
