Adds an experimentalSnapScrollToPinnedItem path that resnaps scroll to
the first pinToEdgeWithInset item after inset/visible-size updates and
on empty itemNodes. Promotes ListViewItem to AnyObject and adds a
pinToEdgeWithInset protocol requirement with a default of false.
Also runs chat history transactions synchronously when updating scroll
around correlated messages, and tightens beganInteractiveDragging weak-
self handling.
