Fuel Waxing - the mechanics of it.

I'm not familiar with the chemistry but when the fuel waxes, does it then remain in that waxed stated regardless of an increase in its temperature? i.e. does the wax remain in suspension within the fuel? Logically, as the fuel temperature increases during descent, it will revert back to its non-waxed state - but is the transition linear or does it have to be warmed "more" to change back compared to the amount of cooling originally required?

The reason I ask is that a period of time in the LAM hold requires a thrust setting probably above final approach thrsut and the fuel will only be getting warmer by the time it's on approach.
