FR: Firebase Analytics - file:// based environment support

Describe your environment

Operating System version: KaiOS 2.5.0
Browser version: Same
Firebase SDK version: 7.12
Firebase Product: analytics

Describe the problem I am developing an app for KaiOS, a fork of the old Firefox OS, for which apps are based on HTML5 + JS. When compiling and running on device, Firebase analytics stops working. I receive an error as follows. I believe the issue is due to the fact that on device the app is served in the browser via a file:// based URL scheme rather than a http:// based scheme.

@firebase/analytics: 
DOMException: A request was placed against a transaction which is currently not active, or which is finished.

In my research, I have found that Cordova, Expo, and other file:// based environments have had issues around the use of IndexDB not being supported, which FA relies on. I can confirm that KaiOS does have full support for IndexDB, however the above issue persists.

Relevant Code:

import firebase from "firebase";
firebase.analytics().setCurrentScreen(screenName);

        firebase.analytics().logEvent("screen_view",
        {   
            app_name: this.AppName,
            screen_name: screenName,
            app_version: this.AppVersion  
        });
