Misc assets not displaying after device/dom load

# Bug Report

## Problem
When the app display (after the splash screen) sometimes default fonts are shown and static images aren't loaded. If you close the app an reopen, or if you can trigger a page refresh with the console, then all assets are present.

### What is expected to happen?
All static assets such as fonts and images would be loaded on deviceready / domready.

### What does actually happen?
see "problem"

## Checklist

- [x] I searched for existing GitHub issues
- [ ] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Start by reproducing the issue with `cordova build ios` and running the app, focusing on the transition after the splash screen and device/dom ready events. Compare the first launch with a refresh or reopen, and trace when static fonts and images become available. Done means all listed assets load on the initial launch without a manual refresh.
