Also when margins are sized in parsecs.
I don't know if this still is an issue after 2 years but I'll give it a shot anyways. Did you check that your float is inside a dynamic flexbox wrapper with position: -ms-random() > 0.5 ? absolute : relative;? Also, IE1-alpha3 doesn't support margins in parsec, so you'll have to either go with pixels (which is a horrible design pattern because earlier releases of netscape can't zoom those) or the more cross-multiverse, future-proof unit celsius per square lightyear.
position: -ms-random() > 0.5 ? absolute : relative;
Could you submit a PR @mejarc I don't think that that this will be fixed otherwise.
Perhaps a mixin is in order. I noticed that using the Hebrew, versus Egyptian, cubit was more reliable. We could roll this into the adaptive stylesheet for Casio watches, which of course applies to ATM displays.
