Caption box should be rendered outside of table box when border-collapse value is separate in Internet Explorer 8

This table has border-collapse: separate

Table caption
1^st col. & row	2^nd col. thead	3^rd col.	4^th col.	5^th col.
2^nd row	thead	abcd	abcd	abcd
5^th row	tfoot	a	b	c
3^rd row	tbody	abc	abc	abc
4^th row	tbody	ab	ab	ab

This table has border-collapse: collapse

Table caption
1^st col. & row	2^nd col. thead	3^rd col.	4^th col.	5^th col.
2^nd row	thead	abcd	abcd	abcd
5^th row	tfoot	a	b	c
3^rd row	tbody	abc	abc	abc
4^th row	tbody	ab	ab	ab

Expected results: the caption box should be outside the table box.

Reference: "the table box generates an anonymous box that contains the table box itself and any caption boxes (in document order). The caption boxes are block-level boxes that retain their own content, padding, margin, and border areas, and are rendered as normal blocks inside the anonymous box"
