FNCPLANNER (FMX) infinite loop with navigate to in cell scrollmode

somewhere in this code:

          smCellScrolling:
          begin
            while (rvs + totalh > vss + ch) do
            begin
              vs := vs + 1;
              cl := MakeCell(ACell.Col, Round(vs));
              rs := 1;
              if rs > 0 then
                toth := RowPositions[cl.Row + rs - 1] - RowPositions[cl.Row]
              else
              begin
                rs := 1;
                toth := RowHeights[cl.Row];
              end;

              vs := vs + rs - 1;
              vss := vss + toth;
            end;
          end;

Can you please put up a sample that demonstrates this? or a code snippet?

This code, it loops when the calculation leads to navigating to the bottom row n(vertical orienntation, cell scrollmode)

procedure TfrmPlannerUI.MakeItemVisible(const AItem: TTMSFNCPlannerItem);
var
  units : integer;
  firstTime,
  lastTime,
  startTimeInView,
  endTimeInView     : TDateTime;
  cell : TTMSFNCPlannerCell;
begin
  if not AutoFitAppointments  then
  begin
    case TimeInterval of
      THPTimeInterval.Unknown: ;
      THPTimeInterval.FiftheenMinutes: units := 15;
      THPTimeInterval.FiveMinutes: units := 5;
    end;
    firstTime := IncMinute(DateOf(SelectedDate), trunc(planUI.TimeLine.DisplayStart*units));
    lastTime := IncMinute(DateOf(SelectedDate), trunc(planUI.TimeLine.DisplayEnd*units));

    startTimeInView := IncMinute(DateOf(SelectedDate), trunc((planUI.TimeLine.DisplayStart+planUI.VerticalScrollBar.ValueRange.Value)*units));
    endTimeInView := IncMinute(startTimeInView, trunc(planUI.VerticalScrollBar.ViewportSize*units));
    cell.Col := -1;
    cell.Row := -1;
    if (IncMinute(AItem.EndTime, 5)>=endTimeInView) then
        cell := planUI.DateTimeToCell(Min(lasttime, IncMinute(AItem.EndTime, 15)));
    if (IncMinute(AItem.StartTime, -5)<=startTimeInView) then
        cell := planUI.DateTimeToCell(Max(firstTime, IncMinute(AItem.starttime, -15)));
    if (cell.Col>-1) and (cell.Row>-1) then
       planUI.Navigate(cell, False);
  end;
end;

We have investigated this here but couldn't reproduce this here. I suppose this happens under certain circumstances. I suppose the code snippet is part of a bigger project, but to fully understand the scope and the reason why this happens, I will need a sample. Please try to recreate it so we can see which settings are used and why it happens.
