• Status: RESOLVED FIXED

Hi Team,

Creating it separate of bug 273734 to track the usage of 'webkitConvertPointFromNodeToPage' and figure out on how to remove this properly without regressing anything.

Webkit Source: https://searchfox.org/wubkat/rev/7bf250e4832adfb28c2bf2bc518ad59958f2ae1b/Source/WebInspectorUI/UserInterface/Views/GradientSlider.js#404

```

var translationFromParentToBody = window.webkitConvertPointFromNodeToPage(this.element.parentNode, new WebKitPoint(0, 0));

```

Just raising, so we can track it.

Thanks!

Something along those lines:

var parentRect = this.element.parentNode.getBoundingClientRect();
                var translationFromParentToBody = {
                    x: parentRect.left + window.pageXOffset,
                    y: parentRect.top + window.pageYOffset
                };
