I don't think that's the case because if i tap slowly (so slowly that libinput
internally registers these taps as 2 separate taps, not one multitap) client
registers that as double click. I can attach that recording too if you want.

I've reduced it to 120 and it doesn't help. If I tap really fast it gets
registered, tapping with normal speed doesn't get registered and tapping slowly
gets registered but libinput recognizes it as two separate taps.
