Error with splash screen when loading app in browser

I’m working on deploying an Ionic app right now and am experiencing a strange error when the app loads in browser. When the app loads, the html5 “photo missing” image appears briefly. Does anyone know what would cause this?

My code is on GitHub at https://github.com/wkyleg/minimal-hn/tree/master/, and is live to view at https://minimal-hn.firebaseapp.com

Thanks!

These are Cordova resources. You can replace icon.png and splash.png and run
ionic cordova resources to generate custom icons and splash screens for your
app. See ionic cordova resources --help for details.

Cordova reference documentation:

Icons: https://cordova.apache.org/docs/en/latest/config_ref/images.html 14
Splash Screens: https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-splashscreen
