Quinn's R

Now, I'm not here to complain about Quinn and how ridiculous she can be at times ;), but I'd actually like to ask about it's interaction with ally CC.

So, when Quinn is in her R and she gets blast-coned by an ally, Tahm Kench W'd, Bard R'd, Kalista R'd, her ult gets cancelled. This is actually really annoying, considering her R takes 2-ish seconds to cast and costs 100/50/0 mana. Past level 16, it's not as bad considering it costs 0 mana to cast, but it costs time and that can be extremely valuable late-game.

I'd like for this to be looked into because while it isn't a super important fix, it can be irritating for the Quinn player and there is no reason why ally CC should cancel her ult.
