Re: [css-flexbox] which margin definition for intrinsic sizing?

I learned today that not all browsers ignore percentage margins for
intrinsic width computations. In this testcase:
http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E%0A%3Cstyle%3E%0A%20%20div%20%7B%20float%3A%20left%3B%20border%3A%20solid%3B%20%7D%0A%20%20p%20%7B%20margin%3A%2010%25%3B%20%7D%0A%3C%2Fstyle%3E%0A%0A%3Cdiv%3E%0A%20%20%3Cp%3Ethisisaword%3C%2Fp%3E%0A%3C%2Fdiv%3E

Chrome/IE 11/Edge overflow the box, whereas in Firefox they don't. I
actually have no idea how they implement this! I'm also unsure what the
spec requires...
