Firefox request access microphone two times when open app

When I open the app on Firefox browser, it's request access to microphone at Permissions Dialog and at Microphones Dialog (after choose)

Permissions dialog

After microphones dialog

For now, browsers have a rudimentary environment for obtaining permissions.
For example: O Chrome I can invoke mediaDevices.getUserMedia({ audio: true }), it shows a popup one time and after allowed by user, the permission is memorized by browser

But on Firefox every time I invoke the method, and after user permission, It ways asked for it again. It's look like a security behavior of Firefox

There are an API https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/permissions/request
to check if I already have permission before ask for it, but this API does not encompass audio feature
With this missing pattern to request permissions to users across the browsers. I can't do much for this now

Maybe with dfb658c can avoid partially this behavior of Firefox, but you still need at least give permission to browser by native popup
