youtube example doesn't work after refresh
https://media-chrome.mux.dev/examples/media-elements/youtube.html
Tested this in Chrome 103/Safari 15.5 on MacOs 12.4
On first load it seems to work on both (I tested this in private mode). Doing a refresh, the page is reloaded but all buttons don't work. No start, skip or whatever possible.
View on first load.

View after refresh.

That is ... really odd
And as a matter of fact. I can repro it. Confirmed
A hard refresh fixes it cmd + shift + r, might be a caching thing in the youtube iframe going on
I've encountered this as well in the https://github.com/muxinc/media-group project.
my fork fixes a bunch and adds some more events etc. I'll try to open a PR soon. https://github.com/luwes/youtube-video-element
