Zhonyas still cancelling brand ulti

just had it happen 2 games in a row where if you activate zhonyas just before the the first bounce hits the champ the spell fizzles out completely. Its getting highly annoying since people are now abusing this. One of two things is happening from what I can see

A. The spell is just being cancelled regardless if someone would be in bounce range B. The spell fizzles because no secondary target is in the initial cast range of brand ulti
