Renaming failure in generic parameter lists

[tothambrus11]

/// Wrapper type for a named tuple element.
public struct N<Name, Type> {
  public var value: Type

  public memberwise init

  public static fun create<K where K == Name>(value: sink Type) -> N<Name, Type> {
    N<Name, Type>(value: value)
  }
}

given<Name, U is Deinitializable> N<Name, U> is Deinitializable {
}
given<Name, TU is Movable> N<Name, TU> is Movable { // renaming TU fails to apply edits
}

Interestingly, go to declaration works from right TU to left TU, but find references doesn't find anything.
