This is not a new problem for me. Since I'm using TaskBar both keyboard and emoji set would appear when I vlick on the smiley. However I've been able to easily avoid this problem by closing my keyboard before opening the set.
Now with the new version (F-Droid) containing the new set both keyboard and emoji bar are being opened when the smiley is being clicked on. I'm on Stock Android 5.1.1.
