startCameraMaxResolution doesn't support a 640x480 webcam

[timbotimbo]

Description

On windows 10 I cannot get a 640x480 webcam to work using the max resolution option.
The readme describes a fallback to default when using max, but that doesn't seem to happen.
Using default resolution does work.

Tried in the latest Firefox, Chrome and Edge.

Reproduction

1. Connect a low resolution webcam (640x480)

2. Visit the example

3. click startMaxResolution
   There is no permission for the webcam requested, the option shows only my secondary virtual webcam.
   (camera permission popup in Firefox, text in Dutch)
   

4. Refresh the page

5. click startDefaultResolution
   This time the permission popup shows both options.
   

6. After selecting integrated camera, the webcam now works properly.
