    Description

      Basic issue is that the matcher records a single array position in match details without any context. There is no validation that the field path of the matched array matches the field path leading to the positional operator.

      > db.f.drop()
      		 
      true
      		 
      > db.f.save( { a: [ 1, 2, 3 ], b: [ 4, 5, 6 ] } )
      		 
      > db.f.update( { a:1,b:6 }, {$set:{'a.$':10}} )
      		 
      > db.f.findOne()
      		 
      {
      		 
      	"_id" : ObjectId("4bc4c770e4db696f077b91d8"),
      		 
      	"a" : [
      		 
      		1,
      		 
      		2,
      		 
      		10
      		 
      	],
      		 
      	"b" : [
      		 
      		4,
      		 
      		5,
      		 
      		6
      		 
      	]
