                    reference box calculation in the MarginBox case
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Hi Team,

While going through Blink's commit, I came across following:

Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=192180

Webkit Source - https://searchfox.org/wubkat/source/Source/WebCore/rendering/shapes/ShapeOutsideInfo.cpp#116

If we can add clamping similar to Blink for the cases where due to negative margin on negative width/heights, we can fix assertion and crashes.

Appreciate if someone can confirm if it is worth fixing and I am happy to do PR.

Thanks!
