Lattès-map bifurcation accumulation conjecture

Let $f$ be a Lattès map on ${\mathbb P^2}$. Lattès-map bifurcation accumulation conjecture. The map $f$ belongs to the closure of the interior of the bifurcation locus. This is presented as a specific expected phenomenon arising from collisions between post-critical sets and hyperbolic repellers in dimension two; the source does not state a resolution.
