CameraZoomPlugin not working with BoundingBox Camera

Bug report

Issue details

The camera zoom plugin doesn't seem to work with the boundingbox camera. In the model.sdf for the gimbal_small_3d, I changed the type from camera to boundingbox_camera. Whenever I send a zoom command to the corresponding topic, it doesn't change the HFOV. Here is the full change:

<sensor name="camera" type="boundingbox_camera">
        <pose>0 0 0 -1.57 -1.57 0</pose>
        <camera>
          <box_type>full_2d</box_type>
          <horizontal_fov>2.0</horizontal_fov>
          <image>
            <width>640</width>
            <height>480</height>
          </image>
          <clip>
            <near>0.05</near>
            <far>15000</far>
          </clip>
        </camera>
        <always_on>1</always_on>
        <update_rate>10</update_rate>
        <visualize>1</visualize>
