In the WebGL platform, the video frequently stops or fast forwards on iOS devices

Unity Version: Unity-2022-3-LTS.20f1
Test Environment #iOS: iPhone 14, iPad Pro 11 (2nd generation)

I created a simple scene in the WebGL platform that plays videos from the Video Player. The video from Streaming Assets is specified by URL, and the footage is played back.

On Android devices and PCs, the video can be played smoothly. However, on #iOS devices, the video often fast forwards or frequently stops, making smooth playback impossible. However, the video can be played smoothly when the site is viewed in PC mode.

Does anyone know what’s going on?

The problematic site can be checked here. You can play the video from a UI button labeled Play/Pause.
