[Moo] In IE element.getStyle( 'height' ) returns real height instead of 100%

[ZsZs]

I'm experiencing 2nd time that if I set element.setStyle( 'height', '100%' 
) than in IE element.getStyle( 'height' ) returns concrete height in pixels 
while the element.style.height property contains 100%.

I'm using the latest mootools-core-1.4.5-full-compat.js version.

FYI.
