Interacting with a SwiftMessage resigns the view controller as first responder

[adamvnovak]

I am keeping an inputAccessoryView always attached to the bottom of the viewController through a method described here. The viewController sets its inputAccessoryView and then becomes the first responder.

However, when a SwiftMessage displays, and the user interacts with it in any way, the inputAccessoryView resigns because the viewController is resigned as the first responder. Here is a video displaying the issue.

Why might user interaction with a SwiftMessage be forcing the viewController to resign as first responder? And how might this be prevented?
