Regression in Scala 2.13-M4: scaladoc silently ignores -Ymacro-annotations flag

[Atry]

Given a macro annotation that renames any class to the_class_name_is_modified_by_myAnnotation

object MyMacro {
  def macroTransform(c: Context)(annottees: c.Tree*): c.Tree = {
    import c._, universe._
    q"class the_class_name_is_modified_by_myAnnotation"
  }


  final class myAnnotation extends StaticAnnotation {
    def macroTransform(annottees: Any*): Any = macro MyMacro.macroTransform
  }

}

and another project that use the annotation

object MyClass {
  @mypackage.MyMacro.myAnnotation
  class MyInnerClass

  def main(args: Array[String]): Unit = {
    new the_class_name_is_modified_by_myAnnotation
  }
}

new the_class_name_is_modified_by_myAnnotation should compile when -Ymacro-annotations is set. However, -Ymacro-annotations is ignored by scaladoc in Scala 2.13.0-M4, while the same macro annotation works when paradise plug-in is enabled in Scala 2.12.6.
