We just discovered one browser (Win8-IE11) in-house who's javascript is now returning a rational number for <element>.style.left, top, width, and height, where it used to only return integers. We found that W3C has said all along that "length" - pixels or otherwise - can be fractional. And we're ok with that; just had to make a small change to accommodate it...
The question is... Anyone know when IE started doing this? We just noticed it yesterday.
