// the dependency graph, and an unexpected error in a dependent crate caused an ICE in the
// unsatisfied bounds diagnostics for traits present in multiple crate versions.

// Setup:
// - two versions of the same crate: minibevy_a and minibevy_b
// - minirapier: depends on minibevy_a
// - repro: depends on minirapier and minibevy_b
