(Just when I thought I've encountered all the strange IE CSS bugs, here comes another one. Is there a name for this double-vertical-padding bug?)
After creating a simple test case that worked perfectly in browsers like FF and Opera, I was surprised to find issues in IE 6 and IE 7. The page below illustrates the problem.
Edit: To view the issue, visit: http://jsbin.com/efele
Open it in both IE and FF to compare.
I'm curious, what is the official name for this bug? (Is it documented somewhere like on this page?) I have experience with other float-related bugs like the 3px jog bug and the double-margin bug, but encountering duplicated vertical padding is new territory.

<body>
<div id="container">
<div id="sidebar">I am the sidebar</div>
<div id="content">I am the content</div>
<div class="clear"><!-- clear! --></div>
</div>
<p>There should be 100px of space above the two floats, but <em>no</em> space below them...</p>
</body>
</html>P.S., After much trial and error, I finally found a fix for the issue in IE. The solution involved explicitly setting a height on my "clear" div, which is currently commented out to showcase the bug. It's frustrating how much time I spent troubleshooting this!
Thank you!
