           Summary: A WKWebView in a UIViewController that is presented

Sample project that reproduces the bug

This is similar to https://bugs.webkit.org/show_bug.cgi?id=165225. When a WKWebView is presented in a modal UIViewControlller and a file picker is displayed (from <input type="file">), taking any actions from within the file browser will result in the file browser modal being dismissed as well as the application modal. The expected result is only the file browser modal is dismissed and the application modal remains.

To Reproduce:
1. Present a UIViewController containing a WKWebView modally
2. The WKWebView should have an <input type="file"> element.
3. Click the "Choose File" button
4. Choose "Browse" from the action sheet that is displayed
5. iOS will present the file browser modally
6. When the file browser modal is displayed, either choose "Cancel" in the top-right or select a file
7. Upon either of those actions, the file browser modal will be dismissed as well as this application modal that contains the web view
8. The expected behavior is only the file browser modal is dismissed and the application modal remains

I've attached a sample project that reproduces this in iOS 11.3, which is also available on GitHub here with an example GIF: https://github.com/zachwaugh/wkwebview-bugs/tree/master/ModalFileDismissal
