iPad Only: Issue with disabling copy/cut with pinch gesture of UIResponder

While testing the iOS 13 (build with XCode 11 beta 3) security features of our app, we discovered:


We used the recommended way to disable the copy/cut with 3 fingers pitch gesture for iPads: overriding "editingInteractionConfiguration" and returning UIEditingInteractionConfigurationNone, but it didn't work for all components.

1. We would like to know if there will be an API for MDMs to disable this gesture for whole device?

2. Is it some kind of bug of UIResponder? Because this method works for every view except for UIWebView on input fields.

Note: Unfortunately we can not replace the deprecated UIWebView right-away, because of security functionality.
