<rdar://122495015>
Reviewed by Mike Wyrzykowski.
Improve Overlay Regions by making them snap to the ScrollView's edges
and use the correct coordinate space.
* Source/WebKit/UIProcess/API/ios/WKWebViewIOS.mm:
(snapRectToScrollViewEdges):
Introduce a new function to snap/clip the OverlayRegion rects to the
edges of the ScrollView.
(configureScrollViewWithOverlayRegionsIDs):
- Generate Overlay Regions for fixed elements that might be part of a
ScrollView ancestor.
- Handle the case where the main scroller is itself fixed.
- Position the Overlay Regions relative to the viewport of the
ScrollView.
* LayoutTests/overlay-region/snapping-expected.txt: Added
* LayoutTests/overlay-region/snapping.html: Added.
Introduce a new test to cover the snapping code.
* LayoutTests/overlay-region/many-candidates.html:
* LayoutTests/overlay-region/many-candidates-expected.txt:
