This has been a thing for as long as I know, but moves that have split damage type, that have an On-Hit effect (On High's Airborne on hit or Hexer's Black Bubble come to mind).

If you dodge both hits, you do not get afflicted.
If you dodge ONE of the hits, you have to roll the affliction chance.
If you get hit by both of the hits, you have to roll the affliction chance.

It's just a bit weird that you have to get a glancing on both hits to not get an affliction chance to roll. Frankly, it might not even be a bug, but I figured I might as well bring it up as a query
