Current Behavior

On Windows, even if you specify the Popup's Size property, the Popup's Content size takes precedence.

Layout as follows.

<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
    x:Class="MauiComm_VerifyPopupStyle.Popup1" 
    Size="100, 100" 
    VerticalOptions="Center"
    HorizontalOptions="Start">
    <Label Text="1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ" TextColor="Black"  />
</toolkit:Popup>

The execution result is as follows.

The Popup's Content Size exceeds the Size specified in the Popup's Size property.
On Android and iOS, the size specified in the Popup's size property takes precedence.
However, it takes precedence as long as it does not exceed the size of its parent.

Next, layout as follows.

<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
    x:Class="MauiComm_VerifyPopupStyle.Popup1" 
    Size="100, 100" 
    VerticalOptions="Center"
    HorizontalOptions="Start">

    <Grid WidthRequest="100" HeightRequest="100">
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="Start" HorizontalOptions="Start" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="Start" HorizontalOptions="End" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="End" HorizontalOptions="Start" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="End" HorizontalOptions="End" BackgroundColor="Blue" />
    </Grid>
</toolkit:Popup>

This is the result of changing HorizontalOptions and VerticalOptions.

HorizontalOptions = "Start" VerticalOptions = "Center"

HorizontalOptions = "Center" VerticalOptions = "Center"

HorizontalOptions = "End" VerticalOptions = "Center"

HorizontalOptions = "Start" VerticalOptions = "End"

HorizontalOptions = "Center" VerticalOptions = "End"

HorizontalOptions = "End" VerticalOptions = "End"

The red line in the execution result is the horizontal and vertical center.
As you can see from the execution result, when VerticalOptions is Center, the vertical position is off center.
Also, if VerticalOptions is End, it will not be displayed to fit in the Popup's Parent.

Next, layout as follows.

<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
    x:Class="MauiComm_VerifyPopupStyle.Popup1" 
    Size="100, 100" 
    VerticalOptions="Center"
    HorizontalOptions="End"
    CanBeDismissedByTappingOutsideOfPopup="False">

    <Grid WidthRequest="100" HeightRequest="100">
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="Start" HorizontalOptions="Start" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="Start" HorizontalOptions="End" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="End" HorizontalOptions="Start" BackgroundColor="Blue" />
        <Grid WidthRequest="10" HeightRequest="10" VerticalOptions="End" HorizontalOptions="End" BackgroundColor="Blue" />
    </Grid>
</toolkit:Popup>

The following are the execution results before and after resizing the Window that displays the Popup.

[Before Resize]	[After Resize]

The position of the Popup is not changed according to the resizing of the Window that displays the Popup.

Expected Behavior

I expected the following.

1. I expected the Popup's Content Size to be limited to the Size specified in the Popup's Size property.
2. If I specified Center for the Popup's VerticalOptions, I expected the Popup to appear in the center of the Window it was displayed from.
3. If I specified End for the Popup's VerticalOptions, I would have expected the Popup to appear so that it fits at the bottom of the Window that displays it.
4. If I change the Size of the Window that displays the Popup, I expected the Popup's position to update as the Window that displays the Popup resizes.
