[Bug][MW] Focused Thunder

The functionality on FT seems to be a bit buggy. If I cast Thunder Focus Tea, pop and instant Enveloping Mist, I can't get the benefit from, say, casting Essence Font while moving.

Same as if I cast TFT, Effuse, then try to Essence Font.

TFT allows me to cast 3 RMs without a CD going on, main buggy interaction seems to be with Essence Font. If Essence Font is your second spell, it just won't work, even if you have a charge of TFT up.
