hide/show explicitly set display and leak data on the element

[Christoph Obexer]

calling hide and show on an element explicitly sets the display property of that element and additionally fails to remove the olddisplay data property

rwaldron did you set it to enhancement by accident? to me this seems like a bug

I don't see the problem here. We want to make sure that the display is being explicitly set and it's not being affected by something in a stylesheet somewhere (and checking for that premise would make the code a lot slower). Additionally, we want to maintain olddisplay so that we don't have to re-query for it again later. I think we're OK here. Please feel free to provide another test case that you think demonstrates otherwise.
