Preserve ResolverDrawerLayout fully collapsed state across relayout

Fix a bug where a relayout that grows the size of ResolverDrawerLayout
content would cause it to get stuck in a half-collapsed state. This
could also lead to janky touch interaction behavior in
onStopNestedScroll as it animates to the fully open/closed state after
clicking in a descendant list.
