STL nested scroll keeps priority even if it cannot scroll
Fixes a bug introduced with ag/29700348.
In an attempt to simplify PriorityNestedScrollConnection declaration, a
new behavior has been introduced: the NestedScrollConnection could lose
priority when it could no longer scroll.
This caused unexpected behavior (see ag/29996647) and for this reason it
has been reverted.
It is now possible to specify when the PriorityNestedScrollConnection
can lose priority during the scroll gesture.
