[MSDK 5.10.0] Thermal video feed keeps switching back to color

Hi! I have a question about the video feed for a thermal camera on M3T.
I use ComponentIndexType.LEFT_OR_MAIN camera to get the stream image, set KeyCameraVideoStreamSource to INFRARED_CAMERA and KeyThermalDisplayMode to THERMAL_ONLY. Everything works fine, but then during the waypoint mission, when reaching a waypoint with the `zoom` action, the video feed automatically switches back to the color camera.
Action looks like this:

<wpml:action>
  <wpml:actionId>1</wpml:actionId>
  <wpml:actionActuatorFunc>zoom</wpml:actionActuatorFunc>
  <wpml:actionActuatorFuncParam>
    <wpml:focalLength>24</wpml:focalLength>
    <wpml:isUseFocalFactor>0</wpml:isUseFocalFactor>
    <wpml:payloadPositionIndex>0</wpml:payloadPositionIndex>
  </wpml:actionActuatorFuncParam>
</wpml:action>

Can I prevent this automatic video feed switching when using the `zoom` action? Is this the expected behavior?
