It seems to be fixed with following Commit:

https://src.chromium.org/viewvc/blink?view=revision&revision=160554

It did changes here:

https://github.com/WebKit/WebKit/blob/9856bc8b756610ac4e3a4a2c480e6332f50e0cd7/Source/WebCore/page/EventHandler.cpp#L1544

Webkit (current):

inResizer = layerRenderer.layer()->isPointInResizeControl(roundedIntPoint(result.localPoint()));

Chrome Patch:

inResizer = layer->isPointInResizeControl(result.roundedPointInMainFrame(), ResizerForPointer);

*** Need to be changed ***

inResizer = layerRenderer.layer()->isPointInResizeControl(roundedIntPoint(result.roundedPointInMainFrame(), localPoint);

If someone can confirm the approach, I am happy to do PR. Only problem / build error might be that it could only accept 1 argument but now we are providing it two. For that, if we can do:

auto joined = roundedIntPoint(result.roundedPointInMainFrame(), localPoint);

and then pass on single argument.

To this:

inResizer = layerRenderer.layer()->isPointInResizeControl(result.roundedPointInMainFrame(), localPoint);
