[csswg-drafts] [css-multicol] What happens to the mbp of the empty fragment created by a spanner being first-child of an element

== [css-multicol] What happens to the mbp of the empty fragment created by a spanner being first-child of an element ==
In working on #1072 I built some tests and noticed something which seems suboptimal. 

Where the spanner is the first child of an element with margin, padding and borders implementations then split those across the columns. [I have a test case here](https://codepen.io/rachelandrew/pen/aYQeqZ/) and below is a screenshot of this in Chrome 65.

The margin is in column box 1, then the top border, then the padding with a left and right border. This seems logical although probably not what anyone wants. Either way, we don't have any text describing what should happen in this case.
