Warframe Archwing control issues

After a little testing it's apparent that the flight control axis isn't locked to the camera axis, like it is in the main game (where your character turns to face the camera's direction before moving forward/left/right).

This means that when you try to move in a direction based on where your camera is pointing, you frequently get arbitrary movement in other directions, making it much harder to control where you're going.

The first segment of this video shows what should be simple left/right strafe movements that for some reason also end up having vertical or forward/backward movement added, while the second shows that forward movement from rest regularly has a similar, arbitrary, off-axis component, making it much harder to fly where you're pointing.
