The subnormal subgroup algebraicity conjecture for division rings

Let $D$ be a division ring with center $F$, let $K$ be a division subring of $D$ containing $F$, and let $N$ be a subnormal subgroup of $D^*$. A division ring or subset is left algebraic (respectively, right algebraic) over $K$ when its elements satisfy the corresponding one-sided algebraicity condition over $K$.

Subnormal subgroup algebraicity conjecture. If $N$ is non-central, then $N$ is left algebraic (respectively, right algebraic) over $K$ if and only if $D$ is left algebraic (respectively, right algebraic) over $K$.

The conjecture asks whether one-sided algebraicity of a non-central subnormal subgroup forces, and is forced by, one-sided algebraicity of the whole division ring. Its resolution is not indicated in the supplied source, so its status remains open.
