Origin null in cordova-plugin-ionic-webview

I had been using the cordova-plugin-ionic-webview plugin for a few months and all was well. Requests came through with a localhost:8080 origin. I’m now seeing requests come through with a null origin which is breaking my API calls. I have tried this will versions 1.2.1, 2.3.1 and 3.0.0 of the plugin. I’ve also seen it with xcode 9 and 10, and on 2 different iOS devices.

Any thoughts about why this plugin would send null origins? If I remove this plugin things work well, but this plugin has UI and performance benefits. The timing of this announcement is a little interesting - not sure if anything changed in the guts of this plugin? Previous builds I had worked fine - new builds are what started sending null.
