Additional details from the original bug:
"In particular, I would have expected the non-detach mode to be much slower if I did anything to invalidate layout, and I would have expected the slowdown to be in layout. As expected, both approaches spend the same amount of time in JS as well as in layout. Unexpectedly, adding the nodes while the elements are attached causes one very long style recalc before layout and paint."
