            Bug ID: 169548
           Summary: Spec change: <img ismap> coordinates should be from
                    image edge, not border edge
    Classification: Unclassified
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM

Expect click on border in the top-left corner to get coordinates 0,0. WebKit measures from the border edge instead.

The test passes in Chromium and Gecko; fail in WebKit and Edge.

> Definitely makes sense just to align with Chrome/Firefox on this...
