IE7-/Win: hasLayout and margins of nested boxes

In all the following test cases a blue box with some margins is inside a pink one. Depending on hasLayout on the inner (blue) and outer (pink) boxes, IE7-/Win shows several anomalies. After each test the IE result are briefly described.

An attempt to summarize the various problems (which are mostly wrong margin collapsing, but not only.) Please note that this is far from being definitive, due to the multiplicity of possible combinations:

A hasLayout outer box always prevents margins on the inner box to stick out of it. In absence of margin/padding this is wrong.
A hasLayout inner box inside a non hasLayout one always has its bottom margin sticking out of the outer box. In presence of margin/padding this is wrong. This can be fixed by an empty element between the closing tags of the two boxes.
In the case of a hasLayout box inside a non hasLayout one with a top border or padding there may also be loss of margins. This behavior is dependent on presence/absence of white space and/or comments between the opening tags of the two boxes. The rows marked with "& comment" have a comment suitably placed in the markup to fix this loss of margins.
In the case of a hasLayout outer box, its top padding collapses with the top margin of the inner box, this is always wrong since padding and margin should never collapse.
