remember when user has pressed "allow access to camera" on page submit

[ghost]

Great library! Is it possible to remember when the user has pressed "allow access to camera"? The reason is that i am validating the qr-code and if its outdated i do a postback and present a popup-warning. At the same time, the page asks "allow access to camera?" every time.

As I know it is an option of the browser to remember the user choice. If a user checks this option, camera permission has been granted permanently.
