When I set a half screen floating panel's backdrop's dismissal tap gesture recognizer to be enabled, only the very top of the screen is the tap target. Is this a reproducible bug?

It's like the half screen floating panel is treated as a near full screen floating panel, since I can only tap to dismiss at the very top.

If you're using the default FloatingPanelBottomLayout, and want the backdropView to always be visible (e.g. to block taps behind the panel), the cleanest way is to subclass it and override only backdropAlpha(for:).

import FloatingPanel

final class AlwaysVisibleBackdropLayout: FloatingPanelBottomLayout {
    override func backdropAlpha(for state: FloatingPanelState) -> CGFloat {
        return 0.3 // or any value > 0 to make it visible
    }
}

let fpc = FloatingPanelController()
fpc.layout = AlwaysVisibleBackdropLayout()
