Will boosters affect HoT masteries?

As far as I know, any experience gained on a lvl 80 character will go towards the active mastery. So if you activate a killstreak booster or normal xp booster and do stuff in the Jungle you would be getting more experience towards your mastery rank.
Atleast that’s what I recall from all the streams etc.
P.S. food buffs work too. Think of the +10 or +15 xp on kill while under the effects of food.
