Splash screen with android inappbrowser bug

### The plugin as it sits handles IOS and Android differently in regards to how it handles the splash screen.
**Use case:** I am launching the inappbrowser on opening of the app, i would like the in app browser to behave like it does on ios ( not close the splash screen on launch of the inappbrowser ). On android it closes the splash screen on opening of the inappbrowser vs when i want it to close (when the inappbrowser page load completes), which causes a white screen until the inappbrowser loads.

Any tips, ideas, or plugin fixes that could make the android component act like it does on IOS and not interfere with the splash screen?

Start by comparing the Android and iOS splash-screen handling in the InAppBrowser plugin, focusing on the behavior when the browser opens during app launch. Reproduce the white screen before the page load completes and compare both platform implementations. Done means Android keeps the splash screen until the InAppBrowser page finishes loading, matching the requested iOS behavior.
