In our application, we separately ask users for access to camera and microphone. However, when a user blocks access to camera in the camera permissions dialog by clicking on "Don't allow", this selection get remembered and automatically applied to microphone as well, without prompting the user with a permission dialog for microphone.

At no point there is any mention of microphone when we ask for camera permissions and even when we inspect the page permissions, it states that the camera has been temporarily blocked, but nothing about microphone.
