This is a limitation of custom highlighting API, existed long time before AIS_Trihedron modification (AIS_Trihedron::IsAutoHilight() and AIS_Trihedron::HilightSelected() are now overridden):

  //! Method which draws selected owners ( for fast presentation draw )
  virtual void HilightSelected (const Handle(PrsMgr_PresentationManager3d)& PM,
                                const SelectMgr_SequenceOfOwner& Seq);

To overcome this limitation, related API methods (e.g. SelectMgr_SelectableObject::HilightSelected()) should be modified to receive style Prs3d_Drawer as in case of Auto Hilight is turned on - see also current implementation of AIS_InteractiveContext::highlightGlobal() which just ignores passed style because HilightSelected() does not receive it:

  if (!aGlobOwner->IsAutoHilight())
  {
    SelectMgr_SequenceOfOwner aSeq;
    for (AIS_NListOfEntityOwner::Iterator aSelIter (mySelection->Objects());
         aSelIter.More(); aSelIter.Next())
    {
      if (aSelIter.Value()->IsSameSelectable (theObj))
      {
        aSeq.Append (aSelIter.Value());
      }
    }
    theObj->HilightSelected (myMainPM, aSeq); ///!<<
  }
  else
  {
    aGlobOwner->HilightWithColor (myMainPM, theStyle, aHiMode); ///!<<
  }
