If there are in a sealed container that wouldn’t matter, unless it flies using a magical force without an equal and opposite force, at which point you might as well just throw out conservation of mass.
For it to be buoyant, density would have to be less than air. If we’re holding to conservation of mass, then the bottle would have to be significantly larger than the paladin, which doesn’t sound particularly stealthy.
It might have the same mass, but considering they gain a fly speed, their (effective) weight is zero.

Buoyancy. It has weight, but if it’s lighter than air, it still floats.

Fun thing about gasses is that they are compressible.
