No, its sensible.  The document is not changing. No mutation events
are being generated. Instead, a local copy of the text contents are
being edited, in the representation.

These *might* be reflected back into the DOM at a later date. Or they
might be sent to a server. or something.

In particular, if there is a 'reset' button, the original contents of
the text area will be used to get back to the original default
editable contents.

Well, if you edit a text area in the DOM its contents will change,
too. If you type into a textarea, you are not editing the textarea
element.

This is normal and expected behavior; chasing up individual messages
is not needed.
