Console log from safari containing the failure

We're observing this issue on the current setups:
MacOS: 13.2.1 Ventura
Safari 16.3, 16.4
It is reproducible every time.

Safari has been given Screen Recording permissions in the System settings.

When we try to share the screen, it fails with this error in the console:
"A MediaStreamTrack ended due to a capture failure"

I tried experimenting with the video constraints while calling getDisplayMedia(). When sending a basic object in as video constraints like below, the screen sharing works perfectly fine.
{
    aspectRatio: 1.777,
    frameRate: 10,
}


However, if we send in video constraints like these, we observe the problem.
{
    "cursor": "always",
    "aspectRatio": 1.77,
    "frameRate": 10,
    "height": 1080,
    "width": 1920
}

{
    cursor: "always",
    frameRate: 10,
    height: 1080,
    idealHeight: 1080,
    idealWidth: 1920,
    maxHeight: 1080,
    maxWidth: 1920,
    width: 1920
}
