/** serves a single purpose - let ZoomText read the drawers ...
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.)
