Pretty sure Qi'ra should read:
While you move and engage , you ignore obstacles that you are locking.
Would have been much clearer since when a ship engages it may perform an attack. I do think Qi'ra will let you attack while overlapping the obstacle her ship has locked but FFG needs to clarify this or we'll have this argument forever.
They specifically changed wording on things to make things clearer but still couldn't word it correctly on some cards.
