Strong Chinburg's conjecture on Mahler measures and Dirichlet L-values

Let $m(P)$ denote the Mahler measure of a non-zero polynomial $P$, let $L'(\,\cdot\,,-n)$ denote the derivative of a Dirichlet $L$-function, and let $\chi_{-f}\coloneqq\left(\frac{-f}{.}\right)$ be an odd quadratic character. Strong Chinburg's conjecture. For every odd quadratic character $\chi_{-f}$ and every $n\in\mathbb{N}$, there exists a non-zero polynomial $Q_f\in\mathbb{Z}[z_1,\ldots,z_{n+1}]$ and a rational number $r_f$ such that

$$r_fm(Q_f)=L'(\chi_{-f},-n).$$

This conjecture concerns the proposed relationship between Mahler measures and special values of Dirichlet $L$-functions. The source presents it as one of Chinburg's conjectures and does not state a resolution.
