FlexLayout inside StackLayout does not adjust height

[sschoeb]

Description

Using a FlexLayout inside a StackLayout does not adjust the height of the FlexLayout.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="BugTestFlexlayout.MainPage">

    <StackLayout Orientation="Vertical">
        <Label Text="Hallo1"></Label>
        <FlexLayout>
            <Label Text="Hallo2"></Label>
            <Label Text="Hallo3"></Label>
        </FlexLayout>
        <Label Text="Hallo4"></Label>
    </StackLayout>
</ContentPage>

On my Android smartphone this looks like this:

The Labels for "Hallo2" and "Hallo3" are not visible.

Steps to Reproduce

1. Create a new MAUI App
2. Use the given XAML above
