Podcasts don't play the first time you press the play button in the Blazor web app

The first time I try to play a podcast using the Blazor web app I get the following exception in the browser dev console:

       Unhandled Exception:
       Microsoft.JSInterop.JSException: The play() request was interrupted by a new load request.

       ThreadPool Callback threw an unhandled exception of type Microsoft.JSInterop.JSException

If I stop play and try to play again the podcast plays fine.

In general, to play a podcast I'm finding I have to click the play button once, pause it, and then play it again to hear sound.

Seems to be caused by c3f31b9. If I revert that commit the audio plays without error the first time you press play.
