Back in 2000, some of the first AFCI's had a .5-7MA class A trip sensitivity, which would trip when a down stream GFCI would trip, whether it be by the test button, or the circuit leakage of the GFCI, after they realized this problem they raised it to 30-50ma, no more problem with having a down stream GCFI on a AFCI.
Funny part is now they can set it back to the 5-7ma and call it a combo AFCI/GFCI and charge you more lol.
Now I think they all are set at 30 ma trip level, which is the same as a GFP
