Proxy Camera component not cropping on live stream

Below are two picture entity cards showing mjpeg cameras, the only difference is the one on the right has

camera_view: live

added to it.

As you can see, the crop is not applying to it
The PR for this mentions the crop mode was not tested on video streams https://github.com/home-assistant/core/pull/18431

Has anyone gotten the crop to apply to the live stream?
