            Bug ID: 233417
           Summary: iOS Safari 15 address bar doesn't respect touch-action
           Product: WebKit
           Version: Safari 15
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: UI Events
          Assignee: webkit-unassigned at lists.webkit.org

Steps to reproduce:

Scroll the page by initiating touch gesture from the green background. Page scrolls, this is expected. Scroll until the address bar disappears.

White box has "touch-action: pan-x" applied. Initiate touch gesture from the white box. Page does not scroll, this is expected.

Attempt to scroll down from white box. Page does not scroll but address bar *does* expand. This is not expected.

This breaks non-native drag gesture implementations.
