Bard portal bug with Camille R

What's the bug? I see Bard trying to go through his portal and being pulled back into Camille's ult like it's supposed to.

Not a bug, "cannot leave" means he is pulled back into it.

What part of "can't leave by any means" do you not understand.

im talking more about the fact that it lets me leave the area through the portal which should be impossible like yes it pulls me back in but i still eft the area and if that portal were longer it would basically negate camille's ult usefulness
