The gasket between the top and the main body also seems to be an opportunity for a "leak". The gasket acts as a wick. However, I am not sure if this problem is a result of a poorly adjusted float. I recall reading that it is not uncommon for the top to warp a little and thus allow a little seepage at the gasket.
