createMediaStreamDestination is not a function
I am having a hard time utilizing the Web Audio API within epiphany. From what I've read, the Web Audio API should be supported in recent versions of the browser, however I cannot create a MediaStreamDestination using this browser.
To reproduce open a browser console and type the following:
new AudioContext().createMediaStreamDestination()
While this works just fine on chromium and firefox, I receive the following error message on epiphany version 41.4 (fedora rpm) and 42.0 (flathub):
TypeError: new AudioContext().createMediaStreamDestination is not a function. (In 'new AudioContext().createMediaStreamDestination()', 'new AudioContext().createMediaStreamDestination' is undefined)
From the mdn docs I can see that almost all browser support this API. Safari, which I take for reference since Gnome Web isn't mentioned in the mdn docs, supports this API since 2012. How can I circumvent this problem? Is there another epiphany-specific API? Is this an issue within WebKit? If so, why does it work on safari?
