Explorer Mac bug - Table as container

In Explorer Mac any table always has position: relative.

Example page.

The table on the example page has an explicit position: static. It contains an absolutely positioned .testdiv. In positioning this div browsers should ignore the table because they should ignore all elements with position: static. However, Explorer Mac behaves as if the table has position: relative and positions the test div relative to the table.

.container {
	position: static;
	margin-top: 50px;
	margin-bottom: 100px;
	border: 1px solid #000000;
}

td {
	border: 1px solid #000000;
}

.testdiv {
	position: absolute;
	top: 20px;
	left: 20px;
	background-color: #AD007B;
	color: #ffffff;
}

Safari: correct

The testdiv element is positioned relative to the browser window and ignores the table.

Explorer Mac: incorrect

Explorer Mac behaves as if the table has position: relative.
