User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

Try to watch video on YouTube, expect VA-API HW decoding.
Logs show

libva info: VA-API version 1.12.0
libva info: User environment variable requested driver 'iHD'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_10
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.12 (libva 2.10.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 21.1.1 ()
vainfo: Supported profile and entrypoints

Actual results:

No HW decoding (checked with intel_gpu_top)

Expected results:

Should be HW decoded. It works for vesion 97.0.2, but does not work for 98 and 99.
