No lossless zoom when HDR is on?

[Airbus]

When "Lossless Zoom Only" is enabled, Anafi doesn't let me to zoom with HDR on

I havent't received my Anafi yet, but makes sense to me: All Video HDR on consumer electronics that I've looked into was based on dual-ISO on sensor, so, it uses twice lines on sensor to capture two distinct exposures, one for the highlights and other for the shadows.
Because of that, the sensor area used to video is almost all vertical space from the sensor, rendering the digital lossless zoom impossible...

That or the HDR processing takes the processing resources that would be needed for proper rescaling.
