Camera access doesn't work in Brave even with shields down (Bitpay)

[bbondy]

Description

When requesting higher limits from BitPay, it asks for a selfie and requests camera access.
If you allow it, even with shields down, the camera is blocked.

On Chrome it works though.

2. Click on "Unlock Higher Limits"
3. Click on Proceed
4. Upload your passport and go to the next step
5. When asked to take a selfie, allow
6. Optionally repeat for the same results with shields down.

Doesn't allow camera access

Expected result:

Should allow camera access
