Description
On Ubuntu 18.04 with Browse 7cfd9f2 and v202, scratch.mit.edu online editor v3.0 does play sound fine, but does not record sound. When an attempt is made, a dialog from the web app is shown, but it is insensitive. There is no WebKit2.UserMediaPermissionRequest sent. Console shows an internationalisation error in the web app;

Attemping to bisect by wrapper, MiniBrowser from libwebkit2gtk-4.0-37 does not render the editor at all.
Works fine with Firefox, which pops up a permission request at this time. If the permission request is refused, the editor remains in the same state as shown by the screenshot above.
https://www.html5rocks.com/en/tutorials/getusermedia/intro references an audio record demonstration at http://webaudiodemos.appspot.com/AudioRecorder/index.html which likewise does not work.
So the cause is a failure to receive and handle the permission request.
