I've implemented a WebM video with the video tag. The alpha channel is displayed correctly in Chrome but not in Firefox nor Edge - there's a black background.

I thought those browsers had good support for WebM? Am I missing something?

Markup looks like this:

 

<video autoplay loop muted poster="example.jpg">
  <source src="video.webm" type="video/webm">
