UWP VisualStateManager.GotoState works not correctly

I have a custom control MediaPlayerControl. In the its Template I define a VisualStateGroup:

<VisualStateGroup x:Name="SizeState">

    <VisualState x:Name="Normal" />

    <VisualState x:Name="LargeSize" >

        <Storyboard>

            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MediaInfo_Border" Storyboard.TargetProperty="(Grid.ColumnSpan)" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="1"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MediaInfo_Border" Storyboard.TargetProperty="(Grid.RowSpan)" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="2"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="PrimaryMediaControl_Border" Storyboard.TargetProperty="HorizontalAlignment" >

                  <DiscreteObjectKeyFrame KeyTime="0" Value="Center"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MediaTransportControls_Timeline_Border" Storyboard.TargetProperty="(Grid.Column)" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="1"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MediaTransportControls_Timeline_Border" Storyboard.TargetProperty="(Grid.ColumnSpan)" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="1"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MoreButton" Storyboard.TargetProperty="Visibility" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="Visible"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SecondaryTrim_MenuFlyOut" Storyboard.TargetProperty="Visibility" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="Collapsed"/>

             </ObjectAnimationUsingKeyFrames>

             <ObjectAnimationUsingKeyFrames Storyboard.TargetName="TrimButton" Storyboard.TargetProperty="Visibility" >

                 <DiscreteObjectKeyFrame KeyTime="0" Value="Visible"/>

             </ObjectAnimationUsingKeyFrames>

         </Storyboard>

    </VisualState>

</VisualStateGroup>

And in the SizeChanged event I call ChangeState() function:

private void MediaPlayerControl_SizeChanged(object sender, object e)

{

    ChangeState();

}

private void ChangeState()

{

    string state = "";

    if (Window.Current.Bounds.Width < 600)

    {

        state = "Normal";

    }

    else

    {

        state = "LargeSize";

    }

    VisualStateManager.GoToState(this, state, false);

}

Although VisualStateManager.GoToState return true and UI change to LargeSize state but in short time it automatically changes to Normal state.

If I use LayoutUpdated event, it work properly, but performance is not good.

Can I use GotoState with SizeChanged event?

I would guess that there are some other trigger which makes your UI go back to normal state but I have no idea what it is. Can you provide more details about your project, like a demo or share us the steps about how we can reproduce this issue?
