See bug 1515799 comment 16 for some context.

I don't have concrete numbers to hand but the overhead for this element seems much higher than for e.g. menupopup and menu elements elsewhere (e.g. the menubar), which is surprising. I haven't dug into this in detail yet. Ideally we should fix this overhead, rather than relying on consumers of this particular element using just-in-time instantiation to avoid frontloading this cost.
