FWIW, Gecko only normalizes absolute lengths, the rest of the units are left untouched. Relevant code is here:

https://searchfox.org/mozilla-central/rev/532e4b94b9e807d157ba8e55034aef05c1196dc9/servo/components/style/values/specified/calc.rs#70

And this particular behavior was changed here: https://bugzilla.mozilla.org/show_bug.cgi?id=1396692 (see the first comment for "old engine behavior" and "old behavior of new engine" in comparison to what's implemented now).
