Bug Report

App freezes/becomes unresponsive if the in app browser is closed by swiping down instead of hitting the Close button.

Problem

What is expected to happen?

I would expect swiping down to have the same result as pressing the Close button and the app to continue to work as normal.

What does actually happen?

App becomes unresponsive, nothing in the UI works, there are no errors thrown or logs shown. Force killing the app resolves the issue.

Information

I'm using _blank for the in app modal, and usewkwebview=yes. Pulling latest master 80feff6 fixes the in app browser not showing up (issue in 3.1.0) but there is still an issue with swiping the browser modal away, which will not work as expected. I have tried various forks and updating other packages but have not been able to resolve.

Command or Code

Open in app browser, when closing, instead of pressing Close button (which works), swipe the modal down to dismiss it. The UI becomes unresponsive afterward.

Environment, Platform, Device

iOS 13.
