Description Yuji Sugiura 2020-03-25 19:44:38 PDT

`navigator.mediaDevices.enumerateDevices()` seems not to return same value for the first time calling and after another.

# How to reproduce

- open web page(no matter which page is) and DevTools(Console)
- call `await navigator.mediaDevices.enumerateDevices()`
  - check the result has `audioinput` and `videoinput` devices
- call `await navigator.mediaDevices.enumerateDevices()` again
  - expect the same result, but it returns `audioinput` and `audioinput`(no `videoinput`)

If you got permission by calling `getUserMedia()` first, it works as expected.
