setting `camera='orthographic'` on `mr-app` doesn't work

sample code: https://codepen.io/lobau/pen/eYaOydm

to get the orthographic camera, you have to remove the flag, and it works.

this should be resolved as part of https://github.com/Volumetrics-io/mrjs/pull/622, checking for confirmation on discord conversation
