There are a number of places where we use the outer size (margin-box size) of a box in layout calculations, e.g. in Flexbox and Grid Layout. We should make sure that we're flooring it at zero in the places where it needs to be floored (and not in the places where it needs to be not floored).

@fantasai and I independently reviewed Flexbox, and think all the outer references are either clamped appropriately or don't need to be clamped (and added a note about it not being clamped in one spot), so I'm removing the flexbox tag.

Ran an audit over grid wrt inner vs outer sizes also.

@fantasai fantasai added css-grid-1 and removed css-flexbox-1 labels Oct 10, 2018
