Research direction
Start by reproducing the failure with the reported sequence: enter and exit VR mode twice on iOS, after the canvas has been resized multiple times. Read the linked three.js and model-viewer issues for comparable behavior, then trace the canvas and WebGL context handling. Done means the context remains usable after repeated VR transitions, or the issue is confirmed as an external Safari bug.
