Don't reset animations/transitions on moveBefore

See https://github.com/whatwg/dom/issues/1255

Animations & transitions should attempt to continue
from where they left off, if possible.

This is done in the following way:
- Animations are not cancelled on removal when in a state-preserving
  atomic move.
- We don't reset the computed style when removing the element in
  preparation for an atomic move.
- We don't clear the layout/style flags, so that the layout is
  recomputed and reattached on the next style recalc.
