RenderLayerCompositor.cpp contains the line auto overflowScrollNodeID = 0; This will overflowScrollNodeID a type of 'int', and can be 32-bit in some builds. However, later in the function, overflowScrollNodeID is used in contexts that expect a ScrollingNodeID, which is a 64-bit value. The mismatch can lead to a build error. Fix this by explicitly giving overflowScrollNodeID the desired type.
