This is all already well-defined. The answers to your questions are,
respectively, only as text nodes, no, no, no. It's just a <textarea> that
can have syntax highlighting or other features, with all that being left
up to the UA to decide, just like with text/plain <textarea>s.

In .value (as opposed to .defaultValue).
This is _exactly_ the same as for a text/plain <textarea>.

You seem to be making unwarranted assumptions about this feature. There is
_absolutely no difference_, from an authoring or DOM perspective, between
a text/plain <textarea> and a text/html <textarea>. The difference is
_only_ from a UA and user point of view, and only in terms of UI.
