GestureRecognizers overlaps in a control

pictos commented 1 month ago

Description

If you've a control with more than one GestureRecognizer, the one that needs less taps to be fired will always fire. For example, let's say that you have this xaml

            <Image
                Aspect="AspectFit"
                HeightRequest="185"
                SemanticProperties.Description="dot net bot in a race car number eight"
                Source="dotnet_bot.png">
                <Image.GestureRecognizers>
                    <TapGestureRecognizer Tapped="OnetapGesture" />
                    <TapGestureRecognizer NumberOfTapsRequired="2" Tapped="TwotapGesture" />
                </Image.GestureRecognizers>
            </Image>

the OnetapGesture will always fire, even if I perform a two tap gesture.

Steps to Reproduce

Run the attached sample
Tap one or two times on the image
See the labels counting the number of times that each GestureRecognizer was fired
