Oversight in slab.c SlabContextCreate(), initial memory allocation size is not populated to context->mem_allocated

Hi,

Both aset.c and generation.c populate mem_allocated in
AllocSetContextCreateInternal(), GenerationContextCreate()
respectively.
aset.c
    /* Finally, do the type-independent part of context creation */
    MemoryContextCreate((MemoryContext) set,
                        T_AllocSetContext,
                        &AllocSetMethods,
                        parent,
                        name);

            
    ((MemoryContext) set)->mem_allocated = firstBlockSize;

            
    return (MemoryContext) set;
}

            
generation.c
    /* Finally, do the type-independent part of context creation */
    MemoryContextCreate((MemoryContext) set,
                        T_GenerationContext,
                        &GenerationMethods,
                        parent,
                        name);

            
    ((MemoryContext) set)->mem_allocated = firstBlockSize;

            
    return (MemoryContext) set;
}

slab.c
does not in SlabContextCreate(). Is this intentional, it seems to be an
oversight to me.

    /* Finally, do the type-independent part of context creation */
    MemoryContextCreate((MemoryContext) slab,
                        T_SlabContext,
                        &SlabMethods,
                        parent,
                        name);

            
    return (MemoryContext) slab;
}
