Bounding Strike and other combat maneuvers don't specify how they deal with each possible condition that they could occur in. There's no exception specified in Bounding Strike, so it would make sense for it to follow the standard rules, that the attack is at disadvantage because you are blind. I would certainly rule that way as DM. I might allow it to mitigate other situations that would impose disadvantage - for example, you wouldn't be at disadvantage from attacking from lower ground, as you jumped.
