Possible J4 Bug [GAMEPLAY]

I think I found a bug with J4 and Bard. Not sure if it is intentional or not, as I know J4 can flag and drag while snared, but I was playing J4 earlier and was ganking bot lane. Their bot lane ran into one of the river bushes to escape vision, and their bard targeted his ulti between me and the bush. I decided to flag and drag into the bush to escape the ulti. His ult still hit me and I turned golden, but my flag and drag still completed and I was able to knock their bard up with the combo. After flag and drag completed, I remained golden and untargetable and unable to move for the rest of the duration of the bard ult effect. So I guess the question is, is J4 supposed to be able to EQ through a bard ult.

I haven't gotten a chance to try and reproduce the bug yet, but I will try once I get some time. I was playing on NA at the time.

Steps to reproduce:

1. Play J4.
2. Have bard ult you and try to flag and drag through it as it is about to go off.
3. See if the animation of flag and drag continues while golden. • Expected result: I would imagine that J4 should be frozen in time, since his flag and drag can be canceled with hard cc. • Observed result: I was able to finish my flag and drag combo while golden and untargetable. Once the animation completed (causing a knockup) I remained frozen until the ult wore off. • Reproduction rate: Have not yet tried. Will update after I get time to do some testing. • System specs: In case you need it. Not sure why it would make a difference though.
