Why YouTube looks different on Safari

I am a Mac user and Chrome is my default browser.

I think to give Safari a try and after using for some time I realise that YouTube looks different on safari compare to Chrome.

Here is a small list of some of the changes:

I tried to search it online and found some answer but not anything convincing.

  • Some say because its different browser but it looks same on Firefox and Opera why only different on Safari? And some changes are not possible due to browser difference.
  • Some say Chrome is the product of Google that's why. But What about other browsers?
  • Some suggest that it is because of giving Mac user a different experience. But what if I am using Chrome on Mac?

From changes it is very clear that this are intentional change not because of any bug or platform change.

Is there any UI/UX advantage like smoothness in Safari or Same design is not possible (Or hard to implement) for Safari? Or something else which I totally miss?
