/fixes #751 Details that consent dialogs may not be displayed while an immersive session is active, and explains that this is a short-term restriction. I chose to go with terminating the session in this case rather than suppressing the consent dialog altogether, since it provides very clear feedback about the error case and doesn't require us to make up new behavior for the permissions in question.

Also pinging @blairmacintyre, though I couldn't add you as a reviewer since you haven't been explicitly added as a collaborator for this repo. (We can change that if you'd like!) |

| There are multiple non-XR APIs which cause user agents to request [=explicit consent=] to use a feature. If the user agent will request the user's consent while there is an [=active immersive session=], the user agent MUST [=shut down the session=] prior to displaying the consent request to the user. If the user's consent for the feature had been granted prior to the [=active immersive session=] being created the session does not need to be terminated. | ||

| Note: This limitation is to ensure that there is behavioral parity between all user agents until consensus is reached about how to securely display these types of prompts. It is not expected to be a long term requirement. |

Details that consent dialogs may not be displayed while an immersive
session is active, and explains that this is a short-term restriction.
I chose to go with terminating the session in this case rather than
suppressing the consent dialog altogether, since it provides very clear
feedback about the error case and doesn't require us to make up new
behavior for the permissions in question.
