Hindman's monochromatic sum-product quadruple question

Let a finite partition of $\mathbb{N}$ be given. Hindman's question. There exist $x,y\in\mathbb{N}$ such that

$$\{x,y,x+y,xy\}$$

is monochromatic. This asks whether every finite coloring of the positive integers contains a monochromatic configuration simultaneously involving two numbers, their sum, and their product.
