Symbol.matchingSymbol returns wrong symbol

[adpi2]

trait A:
  def m(x: Int): Boolean = ???

class B extends A:
  def m: Boolean

Using TASTy Query:

val classB = ??? // symbol[class B]
val mInTraitA = ??? // symbol[trait A.m]
mInTraitA.matchingSymbol(classB, classB).get // symbol[class B.m]

The returned matching symbol is incorrect, it should return symbol[trait A.m].
