removeAttr method doesn't work in IE 8 quirks mode

[[email protected]…]

This seems to only affect quirks mode, so to reproduce:

1. In IE 8, open the developer toolbar and change the document mode to Quirks.
2. use the removeAttr() method on an element.
3. Inspect element; Did it work?

My result was that removeAttr did not work in IE but worked in other browsers (Chrome, Firefox, Safari on both Windows and Mac OS)

I used this test case in quirks mode and it worked:

If you are attempting to remove DOM0 attributes such as class, *don't*. Set their corresponding properties to an appropriate value such as an empty string.
