Symbol.asQuotes doesn't populate the implicit scope

Compiler version

3.6.2

Minimized code

import scala.quoted.*

def withGiven[T: Type](values: List[Expr[Any]])(result: Quotes ?=> Expr[T])(using Quotes): Expr[T] =
  values match
    case '{ $x: t } :: values =>
      '{ given t = $x; ${ withGiven(values)(result) } }
    case _ =>
      result

def withGivenInt(x: Expr[Int])(using Quotes) =
  withGiven(x :: Nil)(Expr.summon[Int].get)

inline def withInt(inline x: Int) =
  ${withGivenInt('x)}

Output

Expectation

Symbol.asQuotes should populate the implicit scope.
Real world use-case: typelevel/cats-tagless#588
See the hack that I had to do (refs here are the implicit parameters of the method owning the quotes q):

    def addToGivenScope(refs: List[TermRef])(using q: Quotes) =
      if refs.nonEmpty then
        try
          Expr.summon[Nothing] // fill implicit cache
          val ctxMethod = q.getClass.getMethod("ctx")
          val ctx = ctxMethod.invoke(q)
          val cache = ctxMethod.getReturnType.getDeclaredField("implicitsCache")
          cache.setAccessible(true)
          val contextual = Class.forName("dotty.tools.dotc.typer.Implicits$ContextualImplicits")
          val modified = contextual.getConstructors.head.newInstance(refs, cache.get(ctx), false, ctx)
          cache.set(ctx, modified)
        catch case _: ReflectiveOperationException => ()
