I've had some experience mixing multitracked drums since about 2010, (as mention the drum "stems" aren't isolated samples...you can buy those things in many place), and there is always bleed and that bleed adds a little cohesive glue to a kit. As mentioned a gate will, often, clean things up with many drum tracks but not the cymbal/ohs.
In fact one usually needs to add just the slightest amount of the sane track to a mix as the OH carry quite a lot of that sound.
Manual volume automation or cutting out the unwanted sections will garner best results but won't be 100% great. For me the OH track often contains excess kick drum "click" so it's a case of EQ rather than automation or gates.
Setting the gate will take time & experimentation.
These things said the Drum Stems project is a great leap forward in control and brings BIAB drums closer to other multitrack drums, drum "stems" is another slightly clunky misnomer. Look at Drums On Demand and you'll find excellent mic tracks that have bleed and, occasionally, annoying bits.
If these things bother you then try programming drums with Slate etc. they will let you control the amount of bleed but take time to learn and, as is often the case, the resultant "programmed" drums are likely overplayed.
