Poppy E(charge) pulling targets back

TL:DR - Poppy's E force pulled after I flashed. Twice. #JediYordles

In my most recent game I was playing Caitlyn in a ranked game and the other team had a poppy. Building an assassin like build while still being tanky, but that's just poppy being poppy, so of course she was all up in my face.

What my real problem with this was that whenever I found my self charged, even though I reacted fast, flashing away before she'd manage to reach my body, only to find my character being drawn towards her after the flash as if she was a jedi out of Star Wars. Simillar to how in the past one could pull characters at last second tp with skarner ult etc. This happend twice in this game btw.

Poppy's E states that "Poppy dashes to the target enemy, dealing them physical damage and carrying them along with her."

Correct me if I'm wrong, but flash is an instantaneous movement, without any cast time or the like. This can't be intended! Right?!

Even if she was able to carry them along with her wouldn't that just lock out flash as a whole, not allow a person to flash, only to be force pulled back?

I might be salty cause we lost, but Poppy herself is vexing enough as she is already, I don't want her to also have Jedi powers.
