Does this fix also address the issues presented in iOS 13.4 as outlined in this forum post, or is that altogether a different problem? https://krpano.com/forum/wbb/index.php?page=Thread&threadID=17424

To quote:

The gyro and VR controls [in krpano] are using the browsers 'devicemotion' event (by default) to get information about the current device rotation state. And in iOS 13.4 that event no longer reports the gyroscope rotation information, only the acceleration information are available. That makes the gyro/VR control working strangely slow and inaccurate.
