Code that requests WebGL contexts from Offscreen canvas when available is crashing on iOS 16.4 beta Code of the form: ``` const canvas = window.OffscreenCanvas ? new OffscreenCanvas(0, 0) : document.createElement('canvas') const ctx = canvas.getContext('webgl2') || canvas.getContext('webgl') ``` is leading to downstream errors in production sites due to ctx being null.
