Adding a filter to a callout breaks the clipping of content #127

I'm using a custom theme. If I apply a filter to a callout like below, the callout content (inside a Panel) will be shown outside the callout while scrolling. In the project.xml, allowhighdpi is set to true, antialiasing enabled, using openfl shared context.

var dropShadow = new DropShadowFilter(7,45,0,0.9,20,20,1,1,false,false,false);
callout.filters = [dropShadow];
