Summary AudioContext audio level reported as zero when tab loses and regains focus

In desktop Safari 12, the audio levels reported by the analyzer (via getByteTimeDomainData) remain stuck at zero when the focus shifts to another tab and returns to the original tab. Sample code here: https://codepen.io/v-kpheng/pen/EBGreB. To reproduce: * Open link in Safari * Notice that audio level changes * In another tab, visit another site and click on an area on the site * Go back to the original tab * Notice that the audio level doesn't change anymore and it stuck at 0
