This is definitely a must in the box-model tab, and in fact, the box dimensions that are shown top left in the tab should probably take this into account. Part of meta bug 1150496.
I think there are 3 pieces of information we can show in the box-model tab for this: 1 - Outline the region that is currently used for box-sizing differently. Right now, the 4 regions are separated by 1px dotted outlines, maybe we could make the one that has the box-sizing thicker and more visible in general. 2 - The "CSS size" should be displayed somewhere 3 - The bounding box size should be displayed somewhere We already do (3), but on its own, it's kind of confusing. I think (1) and (2) would make it clear how the box was sized.

I started a couple of months ago to work on this, but now don't have time anymore. I might restart later, but in the meantime, let me attach an early WIP patch so if anyone wants to continue from here there's already something.
