// PruneFrom removes all nodes beneath the lowest node matching dropRx, not including itself.
//
// Please see the example below to understand this method as well as
// the difference from Prune method.
//
// A sample contains Location of [A,B,C,B,D] where D is the top frame and there's no inline.
//
// PruneFrom(A) returns [A,B,C,B,D] because there's no node beneath A.
