Scene Viewer crashes on Android devices when launching AR from model-viewer

## Description
Scene Viewer crashes immediately or after a few seconds when launching AR
on multiple Android devices. This is happening on our WebAR SaaS platform
(ScanAR) and affects multiple device types.

## Affected Devices
- Redmi (MIUI V816.0.8.0.TGCMIXM, Android 13)
- Multiple other Android devices

## Steps to Reproduce
1. Open this URL on Android Chrome:
2. Upload or view any GLB model
3. Click "View in AR" button
4. Scene Viewer launches but crashes immediately

## Error
JNI DETECTED ERROR: java_class == null
ImplModelView.nSetMode crash in com.google.android.googlequicksearchbox

## Expected Behavior
Model should appear in AR on detected floor surface

## Actual Behavior
Google app (Scene Viewer) crashes to home screen

## Additional Notes
- Same crash happens on other WebAR sites (AR Code etc.)
- iPhone AR works perfectly with Quick Look
- Desktop 3D preview works fine
- This appears to be a Google-side regression
