That causes IE8 Beta 1 to barf with "Element is not defined".
Modifying it to:

if (Element && (el instanceof Element))

or

if (Element) {
if (...) {


gets the same result, it wants a more explicit test:

if (typeof Element != 'undefined' && (...))

Perhaps that's documented on one of the IE8 blogs somewhere...

That's the expected behavior if there is no "Element" variable
defined.
if (Element) { // ...
only works if there *is* an Element variable, and it has a non-falsey
value.

Property, not variable. Of an object in the scope chain.
