A-frame does not resize properly after exiting VR on iOS

[jSwanson99]

Steps to reproduce:

1. Enter VR on iOS (on Safari)
2. Exit VR by changing to portrait
3. Close orientation modal that pops up
4. View does not resize

Picture below looks a little weird but that's what happens when you exit, above the tiny view is the bottom of the properly sized editor.

I believe that this might be being caused by running an outdated version of Material UI. @elenaizotova is working on updating that and fixing everything that it breaks.
