 ``YouTubeVideo`` autoplay and the ability to add extra attributes to ``IFrame``
 ===============================================================================
 
 You can add any extra attributes to the ``<iframe>`` tag using the new
 ``extras`` argument in the ``IFrame`` class. For example::
 
     In [1]: from IPython.display import IFrame
 
     In [2]: IFrame(src="src", width=300, height=300, extras=['loading="eager"'])
 
 The above cells will result in the following HTML code being displayed in a
 notebook::
 
     <iframe
         width="300"
         height="300"
         src="src"
         frameborder="0"
         allowfullscreen
         loading="eager"
     ></iframe>
 
 Related to the above, the ``YouTubeVideo`` class now takes an
 ``allow_autoplay`` flag, which sets up the iframe of the embedded YouTube video
 such that it allows autoplay.
 
 .. note::
-    Whether this works depends on whether the autoplay policy of the browser
-    rendering the HTML allows it. It might not work in every circumstance, and
-    could get blocked by browser extensions.

 Try it out!

     In [1]: from IPython.display import YouTubeVideo
 
     In [2]: YouTubeVideo("dQw4w9WgXcQ", allow_autoplay=True)
