Testcase

Overview: Audio produced by the WebAudio framework Tone.js lags, stutters, and sometimes does not play at all when using Webkit2GTK or on the GNOME Web browser.

Steps to reproduce:
– Run main.py in the testcase
– Press the play button

Actual results: Notes play unpredictably, with different timing each time.

Expected results: Each note should be played 0.5 sec after another consistently.

Build 2020-07-30 on VirtualBox Fedora 32 (bug also occurs outside of a VM)

Doesn't occur on other web browsers like Chrome.
