Hopefully this is fixed in Build 423. I've tested it on Chrome, Firefox, Opera and Edge on Windows, and Safari on iPhone.
It now seems to be working correctly on Firefox again. Thanks!

This should also be improved though I think there are still slight clipping issues.
Chrome now seems to positioned and scale LifeViewer correctly, but now Firefox once again doesn't display LifeViewer at all.
