In iPadOS 26, Apple introduced macOS-style window control buttons (close, minimize, fullscreen) for iPad apps running in a floating window. I'm working on a custom toolbar (UIView) positioned near the top of the window, and I'd like to avoid overlapping with these new controls. However, I haven't found any public API that exposes the frame, layout margins, or safe area insets related to this new UI region. I've checked the window's safeAreaInsets, additionalSafeAreaInsets, and UIWindowSceneDelegate APIs, but none of them seem to reflect the area occupied by these buttons. Is there an officially supported way to: Get the layout information (frame, insets, or margins) of the window control buttons on iPadOS 26? Or, is there a system-defined guideline or padding value we should use to avoid overlapping this new UI? Any clarification or guidance would be appreciated!

Steps to Reproduce: Open the Bing search page in Safari (example URL: https://www.bing.com/search?q=webkit&form=APIPH1&PC=APPL). Pinch-zoom in or out, then return the page to exactly 100% zoom. Rotate the device from portrait to landscape orientation. Observe that the page is incorrectly scaled to a value other than 100%. Rotate the device back to portrait orientation. The page remains at the incorrect zoom level. Expected Result: After returning the page to 100% zoom, changing orientation should keep the zoom level at exactly 100% in both portrait and landscape modes. Actual Result: After returning to 100% zoom, rotating to landscape changes the zoom to a non-100% value, and rotating back to portrait retains the incorrect zoom level.

as i know, i can add a UIWindowSceneDragInteraction to my view to do this. but how can I achieve the same effect in SwiftUI? Is there a way to do it without relying on UIKit?
