Merging Blink Commit:

columnMaxLogicalWidth = std::max(columnMaxLogicalWidth, columnMinLogicalWidth);
                    m_layoutStruct[pos].effectiveMaxLogicalWidth = std::max(m_layoutStruct[pos].effectiveMaxLogicalWidth, columnMaxLogicalWidth);

It does not progress below test case though, we might have other issue in handling colspan, which we might need to fix before doing this.
