Yes, you're right.  I have considered to write
Element.prototype.getElementsByTagName() instead, but that may not be
correct either – with host objects "you never know".

That seems to be reasonable, and I tend to follow this convention
prospectively, even though it seems to be rather uncommon for ECMAScript
and as such potentially confusing for readers.
