Automatic update from web-platform-testsUse the voiceschanged event to wait for SpeechSynthesisVoice instance (#13017) In https://github.com/web-platform-tests/wpt/pull/12317 I noticed that speechSynthesis.getVoices() could return an empty list and is allowed to do so by spec, but not that there's also an event that's fired when the voices are updated: https://w3c.github.io/speech-api/#eventdef-speechsynthesis-voiceschanged Using this improves coverage somewhat. -- wpt-commits: 2d49b1ea2fb2c46765ef5bdb01e287497a7406a9 wpt-pr: 13017
