String interpolator does not work with opaque types

[b-studios]

This might be a duplicate of #7092 and might be related to #11493.

Compiler version

Scala 3.0-RC3

Minimized code

import scala.annotation.implicitNotFound

object bugreport {
  @implicitNotFound("Could not find ${A}")
  opaque type F[A] = A
}

def foo = summon[bugreport.F[Int]]

Output

Could not find 

Expectation

Could not find Int

I opened this individually of #7092 since the behavior was different. But now I verified that there is no difference between opaque types and types. Both do not work in the same way -- so closing this issue again.
