Is this error from youtube or this plugin?

Hi,

I just notice this error in devtools chrome console:

[Violation] Added non-passive event listener to a scroll-blocking <some> event. Consider marking event handler as ‘passive’ to make the page more responsive. See <URL>
www-embed-player.js:606 [Violation] ‘setTimeout’ handler took 167ms
base.js:1319 [Violation] ‘setTimeout’ handler took 63ms
The service worker navigation preload request was cancelled before ‘preloadResponse’ settled. If you intend to use ‘preloadResponse’, use waitUntil() or respondWith() to wait for the promise to settle.

Is this coming from this plugin? or is this from youtube itself?

Anyone else seeing this?
