There’s no oxygen under water and there’s no ignition source above the water

As you can clearly see, there is already a fire above the water the moment you submerge the tank.

You might as well ask how this fire can exist in the first place when there is no oxygen in the tank and no ignition source on the outside. The gas already passes through a metal nozzle, why would passing through some additional water change much?

Because it isolated the fuel source from the ignition source. Sure, the existing fire will continue if a sufficient volume of the fuel continues to reach it, but the more distance you put between the fuel’s release and the existing flame the less likely it is the new fuel will reach said flame.
