iOS: tap_point does not trigger SwiftUI toolbar navigationBarLeading Button

[rafiki270]

Problem

tap_point hits the correct visual position of a SwiftUI toolbar button (verified by blue highlight in Instruments), but the button's action closure never fires.

Steps to Reproduce

1. Build iOS app with SwiftUI NavigationStack + ToolbarItem(placement: .navigationBarLeading) containing a Button
2. Connect AppReveal, get element list with get_elements
3. Find the button element's frame (e.g., kitbaritemhost<baritemview>_1 at frame 20,69,36,30)
4. Tap center: tap_point --args '{"x":38,"y":84}'
5. success: true returned, but button action doesn't fire — view state unchanged

Expected

tapp_point coordinates should trigger the button's action.

Environment

• iOS 26.2 (iPhone 17 Pro, 3x scale)
• AppReveal via HTTP streamable-http transport
• SwiftUI NavigationStack + toolbar buttons

Workaround

Tap coordinates need to be manually offset from reported element frames. Reported frame origin (20,69) doesn't match visual position.

Notes

• tap_element with derived element IDs returns "Element not found" for SwiftUI toolbar items (kitbaritemhost)
• get_elements only shows 4 container elements when fullScreenCover is presented (cannot see elements inside fullScreenCover)

Fixed in the current local worktree. This resolves the iOS toolbar tap/window-targeting issue.
