[regression/8.0.0-preview.5.8529] Grid with a star and an empty auto column leads to an incorrect layout

Description

When using a Grid layout with * and Auto columns and there is no content in the Auto column, the result layout is incorrect.

For example, consider the following Grid layout:

<Grid ColumnDefinitions="*, Auto" RowDefinitions="Auto, *">
    <Label Grid.Row="0" Text="First Name" />
    <Entry Grid.Row="1" />
</Grid>

The above Grid contains children in the * column only, while the Auto is empty. The following screenshot demonstrates how the layout appears initially:

After resizing the window, the layout appears correctly:

The above screenshot is on Windows, but similar problems can be observed on the other platforms as well.

Steps to Reproduce

1. Run the sample project from the provided link.
2. Observe the incorrect initial layout.
3. Resize the window or rotate the phone/tablet.
4. Observe the correct layout after resizing.

@Stedy59 Thanks for the suggestion. I have a workaround for my particular scenario, but it is more involved. I am reporting a regression in the Grid layout that worked well with the latest official version, but was broken in the latest preview, in hope Microsoft would have enough time to fix it before .NET 8 goes official.

So this and #16368 are the same bug.
