Code 128 barcodes in SSRS reports for cloud customers?

I have that font selected, and the correct calculated string, but it does not render a barcode.

                  <TextRun>
                    <Value>=Code.GetCode128EncodedString(First(Fields!Calculated_smwh.Value, "BAQReportResult"))</Value>
                    <Style>
                      <FontFamily>Code128</FontFamily>
                      <FontSize>16pt</FontSize>
                    </Style>
                  </TextRun>
