Steps to reproduce:
1. Create a UIWebView
2. Set its HTML to the HTML attached in repro.html
3. Open the app on an iOS13 beta 5 device
4. Attempt to scroll the page vertically
5. Notice the rubber banding effect

This effect is not seen when following the same steps with WKWebView.

We're not making changes to UIWebView any more. Please migrate to WKWebView, and file bugs for any features that prevent you from doing so.
