iOS Clicks no longer work within a Popup v2

After upgrading CommunityToolkit.Maui from 11.2.0 to 12.2.0 there are breaking changes to Popups, they call it Popup V2.
https://github.com/CommunityToolkit/Maui/wiki/Migrating-to-Popup-v2

Within these popups, iOS ContenButtons no longer work on iOS, i.e. the click does not trigger anything - no animation, no command. The Content itself is displayed fine, it's just not a button anymore.

Example by adding a ContentButton to CommunityToolkit.MAUI Sample Page::

<mct:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
           xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
           xmlns:mct="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
           xmlns:vm="clr-namespace:CommunityToolkit.Maui.Sample.ViewModels.Views"
           xmlns:system="clr-namespace:System;assembly=System.Runtime"
           xmlns:mcb="http://schemas.microsoft.com/dotnet/2024/maui/contentbutton"
           x:Class="CommunityToolkit.Maui.Sample.Views.Popups.ComplexPopup"
           x:DataType="vm:ComplexPopupViewModel"
           x:TypeArguments="system:String">

    <VerticalStackLayout Spacing="12">

        <mcb:ContentButton Command="{Binding ThisPopupWillNotFireOniOSCommand}">
            <Label Text="Click me!" />
        </mcb:ContentButton>
    </VerticalStackLayout>
    
</mct:Popup>

Android is fine. But unfortunately this is a showstopper for us, we will have to rewrite all ContentButtons in all Popups.

Found a workaround for this: you have to set InputTransparent="True" for the child of the ContentButton.

This will work even in Popups v2 on iOS:

<mcb:ContentButton Command="{Binding ThisPopupWillNotFireOniOSCommand}">
 <Label Text="Click me!" InputTransparent="True" />
</mcb:ContentButton>
