Yes in the sense that this is what web browsers do.

No in the sense that this one-way behavior is often not desirable. The
original idea was probably to force the user to make a selection. But for
that, we have `required`. I don't think that XForms should mandate that
things work exactly like in HTML Forms on this point.

(Another example of what not to copy are selection lists in HTML
(`appearance="compact"`): they are usually a bad user interface, and used
very little in practice for that reason.)
