Keep playing audio in sheet-modal

I put an audio element inside a sheet-modal.
Here is a fiddle.
However, whenever the sheet is closed the audio stops as well.
How can i keep hearing the audio even when the sheet is closed?

By putting sheet in app root:

Thanks for the response master. that worked.
However, i hope there would be a solution without the need of putting the sheet in app root.
(My reason: i use KnockoutJS to apply binding to each view. Applying binding explicitly to a div that is separated from it’s related view sounds like a bad practice).

Then you have to use something else, becase sheet on close will be removed from DOM or moved from root to its original position what causes audio to stop playing
