defining existing variable with var statement dumps original

[Jelmer van der Linde]

When defining a variable with a var-statement in the global scope, and window[varname] already exists, window[varname] is deleted before the code block is actually executed. Example with window.Element: http://mirror.ikhoefgeen.nl/mootools/711/element_test.html

The following code in in nightly build 29385:
> document.write(typeof window.Element);
> var Element = 'foobar';
> document.write(typeof window.Element);
results in
> undefined
> string

where omitting the var statement
> document.write(typeof window.Element)
results in the expected
> object

Other browsers, for example Firefox 2.0.0.2 and Opera 9.25 produce:
> function
> string


Tested with Webkit Nightly build 29385, Mac OS X 10.5.1 Intel

Please test again with a WebKit nightly build of r29428 or later.  See Bug 16644.

Works like a charm :-)

Testcase returns 'object' as expected.
