ScrollView and ScrollViewer have different scroll speeds

[DominicMaas]

Describe the bug

As title says, when swapping out a ScrollViewer for a ScrollView, the scroll speed is extremely noticeable.

Steps to reproduce the bug

Create a ScrollViewer and ScrollView side-by-side and compare them.

<Grid Margin="10" ColumnSpacing="10">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

    <ScrollView Grid.Column="0">
        <ItemsRepeater x:Name="ItemsControl_ScrollView">
            <ItemsRepeater.ItemTemplate>
                <DataTemplate>
                    <TextBlock Margin="10" Text="{Binding}" />
                </DataTemplate>
            </ItemsRepeater.ItemTemplate>
        </ItemsRepeater>
    </ScrollView>

    <ScrollViewer Grid.Column="1">
        <ItemsRepeater x:Name="ItemsControl_ScrollViewer">
            <ItemsRepeater.ItemTemplate>
                <DataTemplate>
                    <TextBlock Margin="10" Text="{Binding}" />
                </DataTemplate>
            </ItemsRepeater.ItemTemplate>
        </ItemsRepeater>
    </ScrollViewer>

</Grid>

Expected behavior

Either scroll at the same speed or have a ScrollRatio exposed on the new ScrollView control

Additional context

Īs it expected that ScrollView is the eventual replacement for ScrollViewer?

I have to be honest, I prefer the speed of the newer control.
