Animation does not work in WebXR

[patrickkeenan]

Animation works on quest when the browser is open, but not when its closed. This makes me thing there's a check for window, to make sure its valid. However, WebXR sessions do not have a window object. I can understand that its important to check for a server side rendered component, but maybe there's another way to check rather than using window == "undefined".

A couple example lines

theatre/theatre/core/src/sequences/TheatreSequence.ts

Line 352 in 9083186

if (typeof window === 'undefined') {

theatre/theatre/core/src/coreTicker.ts

Line 25 in 9083186

const stop = (): void => {

did you find the way to solve this problem, we found theatr.js animation will frozen when enter AR or VR mode on quest browser.

No resolution, ended up writing my own animation UI. Ideally this is addressed in the next version.
