Well yeah technically activated abilities "trigger" after the action but Hasbro doesn't see it that way nor should they as it just muddies the issue to call things "automatic triggers and manual activated triggers". It's just easier we all agree to use the short hand "triggered" and "activated" as we because technically everything is a trigger, i.e. "casting" is a trigger as English defines the word but then the word "triggered" standalone within magic become meaningless, i.e. we all understand and the game is better for it, what "cast" means as opposed to "after paying mana, you cast a spell which upon resolution triggers the text on the card" and then have to talk about "cast triggers", etc. Yes that too is a trigger but it's just not useful.
Also I'm not sure they are going to ever fix it, bugs that tend to last years become "features" sadly but I upvoted this request anyways because yeah, it really would make life easier and it USED to work years ago.
