Gas tumbler does not buff gas breath mutations

Tested with 3d cobblers and concentrated tartbeard gland paste. Gas tumbler did not affect corrosive gas damage (density) or dispersal rate. Dispersal rate of confusing gas from mazebeard gland paste cooking effect was not buffed by gas tumbler either (contrary to wiki).

Not at all urgent, but would be awesome if y'all could fix so I can make my true kin gas-breathing gunslinger build viable endgame!
