Describe the bug
The ?t=<time> URL parameter doesn't work on the YouTube embedded player.

Steps to Reproduce

1. Open a video in an invidious instance that properly supports passing the referrer to the YouTube embedded player (the only one I know of that does this is https://invidious.tiekoetter.com)
2. Click on a video that supports embedding (here's an example video that I know does)
3. Hope the description page actually loads and you don't get an error
4. Play the video and click somewhere in the middle
5. Click the (Embed) next to the Watch on YouTube
6. Notice how the embedded player still starts over from the beginning

Additional context
I have no idea if this is simply a case of if the URL parameter needs to be different or if this function is straight-up not even supported by YouTube's official embedded player.

I did find in my browser history that, in mid-2021, I accessed a video on youtube.com/embed/ with the URL parameter ?start=<time> but, because one cannot just manually type a youtube.com/embed/ address anymore, I have no way of being able to test if perhaps ?start=<time> is what is instead used by the official YouTube embedded player.
