Hello 
I’ve noticed the YouTube Music link isn’t playable in post it creates a oneboxed link to the video.
Is there any chance to makes YouTube Music links too to lazy loads like YouTube links?
Here is an example:
https://music.youtube.com/watch?v=d27gTrPPAyk&si=5sgyl-DnCSI3mBBM
I’ve also noticed if I remove the music subdomain before youtube.com then it works because the link is same as default YouTube link.
https://youtube.com/watch?v=d27gTrPPAyk&si=5sgyl-DnCSI3mBBM
I tried to manipulate this link to replace https://music.youtube.com link to https://youtube.com but it only works in composer preview. When I publish the post then the link will oneboxed. I think it should happens from server side so it’s probably a theme component is not enough to achieve this. 
Thank you
