When calling PositionForPoint() on an inline element with continuation,
we need to find the correct block flow to enter. Legacy has such
handling, but NG currently doesn't.

As NG currently doesn't build its own tree, which means continuation
info is only available in legacy layout tree, this patch makes NG
PositionForPoint() reuse the legacy handling code to find the correct
block flow.
