is the channeling on dead target intended?

Sergykid

before the chapter update, having channeling shock staff heavy attack, or radiant from templar, would stop the channel when target died. Now, if i start channeling radiant and the target dies from the first tick, it continues to channel the ability on the dead body. It is now intended to be like this in order to make the player manually cancel the ability? some sort of skillful usage of channeled abilities? Or is a bug that they didn't fix in this week's patch.
