If you try to fill an area which is partly outside of the world (too high or low), it will fail, with the error message "The number you have entered (X) is too small/big, it must be at least/most Y". The command will fail if any part of the selection is outside the world. Instead of failing, it should fill everything it can. This bug causes a lot of problems when executing at entities, and the entity moves close to the void, as it will cause the command to fail.

What's the issue here ? That blocks are not fillable in unloaded chunks is WAI.
Or is it the wrong error message ?
Are you expecting You cannot fill blocks outside of the world ?
MC-32485 is about unloaded chunks (invalid X or Z value), this is about being too high or too low (invalid Y value). They are related, but I think should be considered separate bugs.
@unknown You should update description to reflect what exactly you expected, what happened and why do you think this is bug.
@unknown Some confusion has been going on and you've commented with additional clarification. Including those in the description would be nice.
This is true because anything never exist outside the world.
