Motivation and Context

Fixes #566 by setting modalInPopover to true, disabling the swipe to dismiss feature.

Description

Sets modalInPopover to true, only allowing closing by "Done" button

Testing

Created a pagesheet inAppBrowser and tried to close by swiping down. Got the unresponsive app as described in the bug report. Added my changed, rebuild and tried the same. The inAppBrowser is no longer closed, unless "Done" is pressed.
