Video Player Component has irregular playback speed in Player when using WebGL



How to reproduce:
1. Make sure that a CORS extension is installed and the appropriate settings are enabled in the browser that will be used as Player
2. Open the “Video_Player_Speed_Bug” project
3. Open the “VideoTest” scene
4. Switch Build to “WebGL” (File > Build Settings)
5. Build And Run (File > Build And Run)
6. Observe the video that is played in Player for at least 2 loops

Expected result: the playback of the video is unaffected
Actual result: the playback of the video becomes faster or slower

Reproduced with: 2022.2.0b8, 2022.2.16f1, 2023.1.0b13, 2023.2.0a11
Not reproduced with: 2020.3.47f1, 2021.3.23f1, 2022.2.0b7
