Crackling when screen off on mobile

[dnzkptn]

I have a simple loop player in a React app, consisting of one synth and one Player synced to the transport and another synth playing a pedal note outside scheduling. Things work fine on desktop and mobile browsers, but on mobile, turning the screen off causes crackling. Initially pretty significantly at the moment of turning off the screen, to the extent that the the sound completely disintegrates and even seems to hang altogether for a couple of seconds, then after almost-normal playback resumes, with sporadic crackles every 5-10 seconds. The following Codepen contains a minimal working example of how I'm running things; It doesn't even have the Player, just two synths: https://codepen.io/1857629187/pen/pvzrqPp
The codepen reproduces the problem on my Android phone, and the phone of one other person I asked to replicate.

Since this doesn't happen with the official examples, I'm probably using the library wrong (at least within the context of React). I read the performance and best practices section in the wiki and I don't see anything pertinent to my code. Any help figuring out the problem is much appreciated.
