Xamarin - Expander inside ListView not showing properly on iOs - ios

Question

Hello Im trying to use a Xamarin Toolkit Expander in a ViewCell of a ListView.
On android works as expected without any problem but on iOs looks like the ViewCell is not changing its size and the content of the expander is not usable.
It has a strange behaviour because if I scroll up enough to hide the header looks like the cell resizes itself and the content works fine but when clicking again the header the content hides but the cell keeps on the same size
Here is the xaml code
<ViewCell>
<Frame Margin="0,10,0,0" Padding="0">
<StackLayout Orientation="Horizontal" BackgroundColor="White" Padding="0">
<BoxView BackgroundColor="#FF9A31" HeightRequest="15" WidthRequest="15"/>
<behaviors:Expander Margin="10,0,10,0" HorizontalOptions="FillAndExpand" BackgroundColor="White" x:Name="Expander">
<behaviors:Expander.Header>
