Entry FillAndExpand shrinks everything else. How to fix?

I have a row that contains a label and an entry. I want the entry to fill all remaining free space so I have it set as HorizontalOptions="FillAndExpand". However if the entry contains a very long text it just shrinks the label. How can I prevent that? I want the entry to expand but without changing the label width (the label should be as wide as the text in it). The labels are dynamic so I can't set a fixed width.

Here is a simplified version of the layout I have:

<ListView ItemsSource="{Binding Items}">
    <ListView.ItemTemplate>
      <DataTemplate>
        <ViewCell>
          <StackLayout Orientation="Horizontal">
            <Label Text="{Binding Label}" LineBreakMode="NoWrap" />
            <Entry Text="{Binding Value}" HorizontalOptions="FillAndExpand" />
          </StackLayout>
        </ViewCell>
      </DataTemplate>
    </ListView.ItemTemplate>
  </ListView>

The actual layout is a bit more complex so I can't use an EntryCell...
