bug#43176: 26.1; EWW fails to display text in textarea

[Nicolas Graner]

Whenever EWW renders a page that includes a <textarea> element which
contains text, that text is not displayed.

The reason is that the text of a textarea is not given in an
attribute, as with other input elements, but as the textual contents
of the element.

Specifically, in function 'eww-tag-textarea', the line:
(value (or (dom-attr dom 'value) ""))
should be replaced with:
(value (or (dom-text dom) ""))

Hope this helps,
Nicolas Graner
