== [scroll-animations] let source be explicitly nullable (#5202, #5211) ==
Changes:
 - Fix IDL to make source nullable.
 - In CSS source will accept 'auto' and 'none' with none
   mapping to null.
 - In JS, we now map missing 'source' to document scrolling element
   (i.e., auto behavior) and explicitly null 'source' to null.
 - Correctly check null source when calculating offsets.

Other minor cleanups.
