[csswg-drafts] "contain exactly" should be a defined term (#4950)

nigelmegitt has just created a new issue for https://github.com/w3c/csswg-drafts:

== "contain exactly" should be a defined term ==
From #4938, I noticed the phrase "contain exactly" was used but not defined. I imagine it is intended to mean that it is the _smallest_ size possible that completely contains the margin boxes, but it would be worth being explicit about this, since any extension relative to that size would still contain the boxes. 

It is probably implicit that the result is intended to be a simple rectangle, but given that the union of boxes being contained might not be a simple rectangle, we should also make that explicit.
