Content advisory http request error

[bingledore]

Whenever trying to play a video that has a content warning popup, it give an http request error and cannot play any videos with the tag.

For example, most police bodycam videos have these warnings, and do not work.

This is known issue with age-restricted videos in Invidious iv-org/invidious#2189

If you open this random police bodycam video https://www.youtube.com/watch?v=bvZCou0y9cI in a private navigation window, it will show this message

That's why the video does not play. Additionally, the video also does not play on Invidious in the browser.
I will close this issue in favor of iv-org/invidious#2189 once it is fixed, this won't be an issue on Playlet anymore.
