WhatsApp "Background" Camera Access?

[LCBXX]

Whilst reading a message on WhatsApp earlier, I rotated my phone and the display switched into landscape mode.

As it switched, I caught a glimpse of myself, as seen by the selfie camera, in between the frames whist the display was switching to landscape. Does this mean WhatsApp has at least one of your cameras on whilst it's running, regardless of whether your taking a picture or texting?

Android 9, WhatsApp 2.19.360.

Interesting?
I taped the front camera off and my Huawei actually gave me a warning that my camera view was blocked
