source of elemental ailments from ground effects you've created?

i saw this triangle on the tree with 30% increase from recent chill/ignite/shock and was curious about how ground effects interact with this. for example, if you threw out a frostbolt, and enemies stepped on the chilled ground left behind, have you chilled the enemy? or similarly with burning inscription support, the text states the ignited ground is its own spell with damage based on your maximum mana. ground effects' sources do seem to be considered for whether or not they affect the player character so i wasn't sure about this particular interaction and couldn't find much online.
