+
+        Strange enough, ZoomText does not read the drawers when they get the focus (in none of the combinations
+        of AccessibleRoles I tried), except when it does have an AccessibleChild with the role LABEL. To "inject"
+        such a child into the A11Y hierarchy, we use this window here.
+
+        (We could also inject the A11Y component on the A11Y level only, but this would mean additional code. With
+        this approach here, VCL/toolkit will take care of creating and maintaining the A11Y component for us.)
