  We consider a hybrid quantum Hall-superconductor system, where a
superconducting finger with oblique profile is wedged into a two-dimensional
electron gas in the presence of a perpendicular magnetic field, as considered
by Lee et al., Nat. Phys. 13, 693 (2017). The electron gas is in the quantum
Hall regime at filling factor $\nu=1$. Due to the Meissner effect, the
perpendicular magnetic field close to the quantum Hall-superconductor boundary
is distorted and gives rise to an in-plane component of the magnetic field.
This component enables nonlocal crossed Andreev reflection between the
spin-polarized chiral edge states running on opposite sides of the
superconducting finger, thus opening a gap in the spectrum of the edge states
without the need of spin-orbit interaction or nontrivial magnetic textures. We
compute numerically the transport properties of this setup and show that a
negative resistance exists as a consequence of nonlocal Andreev processes. We
also obtain numerically the zero-energy local density of states, which
systematically shows peaks stable to disorder. The latter result is compatible
with the emergence of Majorana bound states.
