The problem could be calculated if aluminum sulfate were stable at the melting point, but this is not the case.

I don't see how the decomposition changes amount of Al produced in the electrode process?

Melting point of Al2O3 is much, much higher

It makes the process unrealistic, still doesn't change the applicability of the Faraday's law.

I formally agree with your statement but it should be clearly stated in the task, as for example in gas tasks it is advisable to treat real gas as an ideal gas.
Students remember all the nonsense best.
