The bulge is gas from the electrolyte breaking down inside the cell. The cell is already damaged; the swelling is the symptom, not the problem. Heat, pressure or a puncture turns the gas into a fire that water does not put out.
Potential consequences
Thermal runaway: the cell heats itself faster than it can cool, and neighbouring cells join in
A fire that reignites after it looks out, sometimes hours later
A cracked screen or case from the swelling, which is what usually gets noticed first
A phone that works perfectly right up to the moment it does not
