            Bug ID: 176992
           Summary: getBBox() called on a <g> with <path> returns a
                    bounding box that includes control points
           Product: WebKit
           Version: Safari 10
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: zbynek.stara.internet at hotmail.com
                CC: zimmermann at kde.org

When getBBox() is called on a <path> element, the correct bounding box is returned (one that does not include path control points).
However, when the same <path> is wrapped in a <g> element, and getBBox() is called on the <g>, the returned bounding box includes the path's control points.
The bounding box for a <g> wrapping a <path> should be the same as the bounding box of the <path> on its own.

This jsfiddle illustrates the problem: http://jsfiddle.net/3t8u9qyb/

Bug is present in Safari 10.1.2, Google Chrome for Mac 61.0.3163.91 and Google Chrome for Windows 62.0.3202.18 .
Also present in Safari for iOS (10.3.3)

Firefox on Windows, IE11 and Edge all show the correct behavior.
