When printing [1] (and other pages from the spec) in a debug build on Windows with e10s, the content process hits the assertion at [2] and crashes.
I don't know if this is cross platform.

Explanation in the patch commit msg.

AGR's _still_ have way too many subtleties, despite recent efforts to simplify them. :(

Ugh, totally forgot about printing and it's weird frame structure. Thanks for fixing this!
