AutoSuggestBox: PlaceholderText is not vertically centered anymore.

[peymanr34]

Describe the bug

There is a regression where PlaceholderText for the AutoSuggestBox is not properly aligned anymore. I noticed this while updating Microsoft.WindowsAppSDK in a small project from 1.5.240607001 to 1.6.250108002 (latest).

Steps to reproduce the bug

1. Create a new Black App, Packaged (WinUI 3 in Desktop) project.

At the time of writing, the latest package version for Microsoft.WindowsAppSDK would be:

<PackageReference Include="Microsoft.WindowsAppSDK" Version="1.6.250108002" />

2. Modify the MainWindow.xaml:

<Grid Margin="5">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <AutoSuggestBox
        Margin="5"
        PlaceholderText="Search for something here..."
        QueryIcon="Find" />
</Grid>

3. You can see the PlaceholderText is not centered vertically:

But if you write something, the actual text will be aligned as expected:

Expected behavior

If you change the Microsoft.WindowsAppSDK package version to 1.5, for example:

<PackageReference Include="Microsoft.WindowsAppSDK" Version="1.5.240607001" />

You can see the PlaceholderText is aligned as expected:
