focus 3 streaming webvr content via steamVR fails in PC browser

[DT-META]

When I use vive focu3 to stream webxr content in the PC browser, the helmet does not display any content, but when I stream games in steam, the helmet can display normally, and even stranger, when steamvr streams without the joystick connected, only the helmet is connected, it can stream webxr content in the PC browser through steamvr, and once steamvr detects the handle and connects to it, it will immediately exit the content of the streaming browser.

Device: vive focus3

Software: steamVR VIVE business streaming are the latest version, and and the device is well connected
