Issue summary:
Provide a brief summary of the issue you're experiencing.

Steps to reproduce issue:
1. Copy the code into your html webpage to embed the button, found at https://developers.google.com/youtube/youtube_subscribe_button. Make sure to click "my application listens for button events".
2. Open developer tools on your browser and open the webpage you have copied the code to embed the button in.
3. Observe the error in the console:
VM239 subscribe_embed?usegapi=1&channel=koldstudios&layout=full&count=default&origin=http%3A%2F%2Fl…:22
Uncaught ReferenceError: __ytRIL is not definedonload @ VM239 subscribe_embed?usegapi=1&channel=koldstudios&layout=full&count=default&origin=http%3A%2F%2Fl…:22
2landingpages.min.js:1 interval

Expected output:
What do you expect to see after performing the above steps?

I expect there to be no error on the page, and that the subscribe/unsubscribe events that happen when the button is clicked to be accurately fired.

Actual results:
What do you actually see after performing the above steps?

There are one or multiple errors depending on what 'data' attributes you set in the html tag that displays the button, and events from clicking the subscribe/unsubscribe button are not fired and consequently event handlers that listen to these events do not perform any action.
