Bogomolov property conjecture for elliptic torsion fields

Let KK be a number field and let EE be an elliptic curve over KK. Write EtorE_{\text{tor}} for the torsion subgroup of E(Q)E(\overline{\mathbb{Q}}), and let K(Etor)K(E_{\text{tor}}) be the field generated over KK by the coordinates of the torsion points. Bogomolov property conjecture. The field K(Etor)K(E_{\text{tor}}) and the group E(K(Etor))E(K(E_{\text{tor}})) have the Bogomolov property. This generalizes Habegger's theorem over Q\mathbb{Q}; the equivalent finite-extension formulation is expected to hold, while the statement is proved for elliptic curves with infinitely many supersingular primes, in particular for curves over number fields with a real embedding.
