[Bug] Label inside nested Grid takes too much height

[viktorszekeress]

Description

I have a Label in the Grid. This Grid is then placed in the another Grid:

        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition />
            </Grid.ColumnDefinitions>
            <Grid Grid.Column="0">
                <Label BackgroundColor="LightSeaGreen" Text="Abc" />
            </Grid>
            <Grid Grid.Column="1">
                <Label BackgroundColor="Orange" Text="Def" />
            </Grid>
        </Grid>

"Abc" Label takes properly only the height it needs.
But "Def" Label takes 3x of the height it should require.

Steps to Reproduce

1. Open the attached solution
2. Observe the wrong label size in different scenarios

Expected Behavior

Label should always take only the size it requires.

Actual Behavior

Label requires 3x more of height.

Basic Information

• Version with issue: 4.5.0.617
• Platform Target Frameworks:

Workaround

If it's a simple Grid, same look and behavior can be achieved with StackLayout:

        <StackLayout Orientation="Horizontal">
            <Grid>
                <Label BackgroundColor="LightSeaGreen" Text="Abc" />
            </Grid>
            <Grid HorizontalOptions="FillAndExpand">
                <Label BackgroundColor="Orange" Text="Def" />
            </Grid>
        </StackLayout>

This behavior seems incorrect:

Same problem here. I encountered this issue twice now in 1 project. In one occasion the row height was too large when the label text was empty. Turned out the row height decreased when the text length increased. I ended up setting a fixed height because auto and * had the same problem.

This is biting us as well.
It is also hindering us from preparing our XF app for a move to MAUI. Because we can't replace our StackLayouts with Grids. And we have to replace those, because we can't use ScrollViews and ListViews inside StackLayouts in MAUI.

This a real shame. It's been 2.5 years since I reported the issue. This is a crucial layouting system Microsoft, this must work as expected.

Any word on a fix for this? I saw someone used ColumnSpacing="0" on any Grids that contain labels like this to work around the issue. That didn't work for me, however.
I'm still seeing it in Xamarin Forms v5.00.2545
