Re: [css-writing-modes-3] 16 margin-collapsing tests submitted

Gérard,

I have reviewed margin collapse tests.

- margin-collapse-vrl-022.xht and margin-collapse-vlr-023.xht
"
Test passes if the top square has a layout identical to one of the squares
below it.
"
I could not understand why the rendering result of this test-case is
determined to the ONE result.
Could you explain that?

- margin-collapse-vrl-024.xht and margin-collapse-vlr-025.xht
I could not understand what these test intent.
It seems to me that there is no margin collapsing because two elements of
div.widthless have only left margin.


- filing bug
I will file the bug in margin-collapse-vrl-022.xht and
margin-collapse-vlr-023.xht.

Hajime.
