Another IE Sliding bug, the weirdest (some elements disappear and others not on SlideDown)

While building my application with jQuery I found out this really weird internet explorer bug:
- When applying SlideDown to elements that are relative positioned or that have relative positioned parents, some elements just disappears.

Performing some tests i found out some actions that brings all or at least some elements back:
- Edit ANY container or child elements' css property live with IE Devoloper Toolbar
- Fade effects in any part of the page
- While the slider is sliding up

This is so far the weirdest IE bug I could notice.

Click to Toggle, when it slides down some elements are going to disappear

You are not using MSIE, in order to notice the bug you got to move to IE
