When both relative layout width and height constraint is set, child layout is not getting focused.

[SahanaSShetty]

Description

When I add both relative layout width and height constraints to the stack layout, the Child layouts are not getting focused. It works if I use either height or width constraints but not both.

Steps to Reproduce

1. Add relative layout height and width constraints in the stack layout
2. Add Entry view and Button inside the stack layout.
3. Focus on the Entry view, it should pop up the keyboard on focus.
4. Keyboard is not popping up.

Snippet:

<?xml version="1.0" encoding="utf-8" ?>
<rel:RelativeLayout
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:rel="clr-namespace:Microsoft.Maui.Controls.Compatibility;assembly=Microsoft.Maui.Controls"
    x:Class="Example.DemoClass"
    Padding="10" >
    <StackLayout Padding="15" HorizontalOptions="Fill" VerticalOptions="Center"  rel:RelativeLayout.HeightConstraint="{ rel:ConstraintExpression
            Type=RelativeToParent,
            Property=Height,
            Factor=1,
            Constant=-40}" rel:RelativeLayout.WidthConstraint="{ rel:ConstraintExpression
            Type=RelativeToParent,
            Property=Width,
            Factor=1}">
        <Label Text="{Binding WelcomeMessage}" HorizontalOptions="Center" VerticalOptions="Center" Style="{DynamicResource TitleStyle}" Padding="0,0,0,10"/>
        <Label Text="{Binding Hint}" HorizontalOptions="Center" Padding="0,0,0,20"/>
        <Entry Text="{Binding UserId}" Placeholder="{Binding Placeholder}" VerticalOptions="Center" ReturnType="Done" Keyboard="Email"/>
        <Button Text="{Binding ActionButtonTitle}" Command="{Binding RegisterCommand}"/>
    </StackLayout>

I have tried with the latest VS (Version 17.6.0 Preview 1.0), but the issue still exists. Please find the repository: https://github.com/SahanaSShetty/MauiExample

I'm getting the below error if I use the relative layout.

@shanselman Can you try to build you Design using this : https://github.com/xtuzy/SharpConstraintLayout or Absolute layout may be since Relative is deprecated

@SahanaSShetty That exception is because UseMauiCompability needs to be called on the App Builder, to enable Compatibility library features like RelativeLayout. That exception should actually be a different exception, with a clear exception message that indicates the exact cause and how to fix it, but apparently the user friendly exception gets turned into the non-user friendly exception in this scenario. That's a problem on the MAUI side, and it took me a little while to track this down, but it's a separate problem than this bug and we'll look to fix it separately.

As for this bug, after I added the UseMauiCompatibility call as shown below, I wasn't able to reproduce the bug - I was able to set the focus to the edit control on Android, with the keyboard popping up. Are you able to reproduce, after adding UseMauiCompability?
