SwiftUI: Shadow glitch after context menu - swiftui

Question

I have a rectangle with a shadow and a context menu. When I close this context menu the shadow of the rectangle appears with a delay (~0.5 seconds). Both the shadow of the complete rectangle as well the shadow of the inner elements. I'm not sure what I am doing wrong.
struct Playground: View {
var body: some View {
VStack(alignment: .leading, spacing: 4.0) {
Spacer()
HStack {
Spacer()
Image(systemName: "house")
.font(.system(size: 50))
Spacer()
}
Text("SwiftUI for iOS 14").fontWeight(.bold).foregroundColor(Color.white)
Text("20 Sections").font(.footnote).foregroundColor(Color.white)
}
.frame(width: 200, height: 300)
.padding(.all)
.background(Color.blue)
.cornerRadius(20.0)
.shadow(radius: 10)
.contentShape(RoundedRectangle(cornerRadius: 20))
.contextMenu(menuItems: {
Text("Menu Item 1")
Text("Menu Item 2")
Text("Menu Item 3")
})
}
}

I found a hacky way to mitigate the issue. This is using pure UIKit and Objective-C but it might be able to be done in SwiftUI too in one way or another.
This is a temporary direct-via-subview access to the view that animates, and I simply attach a shadow to it. This way the animating view will have a shadow and when the REAL shadow pops in, it does so below this shadow. The result looks fine.
-(void)contextMenuInteraction:(UIContextMenuInteraction *)interaction
willEndForConfiguration:(UIContextMenuConfiguration *)configuration
animator:(id<UIContextMenuInteractionAnimating>)animator {
// TODO: Find view dynamically /safer
UIView *platter = (UIView*)self.view.window.subviews[1].subviews[1].subviews[0];
platter.clipsToBounds = NO;
platter.layer.shadowOffset = CGSizeMake(0, 0);
platter.layer.shadowRadius = 5;
platter.layer.shadowOpacity = 0.5;
platter.layer.shadowColor = [UIColor blackColor].CGColor;
}
This works in iOS 13. Have not tried on iOS 14.
