PlatformScaffold causes interference with Webview

[philm001]

Hello all,

I recently ran into an issue with the Platform Scaffold where if I combine it with a webview, the webview fails to load properly in some cases. This is for only iOS. I have a test app that I created that demonstrates the problem which I will be linking below.

In my test app, I have 2 different webview controllers.

Observations:

1. With the platformscaffold, if the app starts on the index of the webview controller, it loads correctly. (webview prime)
2. If the user switches tabs to the other webview (webview secondary), then the secondary one fails to load. It only displays a white screen. However, everything in the data structures is indicating that the page loaded successfully
3. If the user switches back to webview prime, the webview loaded a white screen.

In the repo, I have included the regular scaffold widget which does work, this is meant for comparison between the platformscaffold and the regular scaffold widget. I would prefer to get the platform scaffold working.
