Description

Changing the App Shell tab icon using style triggers causes the tab bar icon to shift and rearrange on icon change.
Works fine in IOS.

Steps to Reproduce

1. In App shell XAML add the style

 <Shell.Resources>
        <Style TargetType="ShellContent" x:Key="NotificationStyle">
            <Style.Triggers>
                <Trigger TargetType="ShellContent" Property="IsChecked" Value="True">
                    <Setter Property="Icon" Value="message_read"/>                  
                </Trigger>
                   <Trigger TargetType="ShellContent" Property="IsChecked" Value="False">
                    <Setter Property="Icon" Value="message_unread"/>                  
                </Trigger>
            </Style.Triggers>
        </Style>
    </Shell.Resources>

2. Apply to the tab
   <ShellContent Title="Notifications" Style="{StaticResource NotificationStyle}" ContentTemplate="{DataTemplate local:NotificationsPage}" Route="NotificationsPage"/>

I am having the same issue, the menu icon jumps into existence on every page load when setting the icon using code behind, and looks janky

Same issue here. Strange shuffling happens when changing icons from codebehind / viewModel.

I have the same issue. It only happens on android. I hope this gets fixed

This also occurs if you change the IsVisible property of a tab.
