Xamarin forms 4.4.0 gives layout issues on Android

[galadril]

There is a layout issue if you update the Android/Xamarin Forms libraries like shown in the screenshot below:

Then the visibility of the label/horizontal view isn't set correctly anymore when you use the tab button. It is still working if you set the SelectedTabIndex (so dont use the button).

I've changed the code of the control a bit, so it works on the latest fast renderers on Android.

<?xml version="1.0" encoding="UTF-8" ?>
<Grid
    x:Class="Xam.Controls.TabButton"
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    IsClippedToBounds="True"
    RowSpacing="0">
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="1" />
    </Grid.RowDefinitions>
    <Button
        x:Name="TabButtonView"
        Grid.Row="0"
        Margin="-2,-3,-2,0"
        Clicked="TabButton_OnClicked" />
    <BoxView
        x:Name="HorizontalIndicator"
        Grid.Row="1"
        HeightRequest="2"
        InputTransparent="True"
        IsVisible="False"
        VerticalOptions="End" />
</Grid>

So I've set the horizonal line to the second row of the grid, with height 1 on the grid
