This test requires WebKitTestRunner. To verify manually, load this page in a web view that has a scroll view top content inset, and scroll such that the full top content inset area is visible. Check that starting a text selection loupe gesture near the top of the top of the document and dragging upwards does not thrash the scroll view's content offset."); |
