iOS 13 introduced a new default modal presentation style that allows the user to dismiss with a downwards gesture. Unfortunately this interferes with dragging from one star rating to another in Cosmos.

To reproduce:

1. Add a CosmosView to a view controller and present it modally on iOS 13.
2. Attempt to drag your finger from one star to the next

Expected: the star rating changes as the user drags her finger

Actual: the star rating does not change

A few observations:

• I am using the latest version of Cosmos and iOS 13.1.1
• The CosmosView works as expected if the view controller's modalPresentationStyle is changed to .fullScreen
• On close inspection, a drag gesture does allow for value changes of half-step increments, but as soon as the gesture leaves one star for the next star, the gesture is dropped.
• Setting the parent scroll view's canCancelContentTouches to false does not seem to help.
• Setting passTouchesToSuperview to false does not help.
