App freezes on iphone, after the opened web page is pulled down to close using in-app-browser

[rajashekaranugu]

On Iphone, when I open a webpage using in-app-browser. The opened web page can be pulled down to close. (do not use close button at the bottom, but just pull the page down from the extra white space at the top and it will be closed).

Problem

After web page is closed app freezes.

What is expected to happen?

on iphone, the scroll down to close option should be disabled.

where as now on ios, It is possible to close the web page just by pulling down
