Boxview Overlay page to inactive controls don't work

[auriou]

with MAUI you can no longer make buttons inactive by placing a BoxView or a Frame over it with an opacity. It worked with xamarin. This is useful for example in the case of an activityIndicator to prevent the user from clicking on other buttons when a process is in progress

Sample

<ContentPage.Content>
  <Grid>
         <Grid>
                 <Button Text="click" Command="...."/>
          </Grid/>
         <Grid RowDefinitions="*,150,*">
                  <BoxView
                      Color="Gray"
                      Grid.RowSpan="3"
                      BackgroundColor="Gray"
                      HorizontalOptions="FillAndExpand"
                      Opacity="0.5"
                      VerticalOptions="FillAndExpand" />
                  <ActivityIndicator
                      Grid.Row="1"
                      IsEnabled="True"
                      IsRunning="True"
                      IsVisible="True" />
        </Grid>
   </Grid>
</ContentPage.Content>
