window.requestAnimationFrame not working in newest 33.3 Meta browser in WebXR mode

I used window.requestAnimationFrame inside a WebXR app, which previously work fine in the Meta Browser, but it seems automatically update to 33.3 on June 3rd, and now this function only works when I press the Meta button to pop up the browser but not work at all when I hide the browser and enter the XR mode.

Any helps? Maybe I need to change the function? But I don't see an alternative to count frames accurately. Basically I want to have a timeManager that supervise the timing of different assets in the app.
