The Most Toys doesn't interact with Destructive Play?

Most Toys:
"Defeating a Map boss while witnessed by the Maven has a 10% chance to count as an additional map being witnessed"

Destructive Play:
"The Maven Summons 1 to 3 additional map bosses while witnessing Map Bosses. These map bosses count as final map bosses"

So for those who've taken these 2 nodes, have you noticed the 1-3 map bosses ever triggering The Most Toys? I knew going in that these 1-3 bosses wouldn't count as just straight up extra witnesses. But the working on Most Toys should still proc on those additional map bosses and after about 20-30 bosses, I haven't noticed it proc yet. It could be a really unlucky stretch of bad luck, but I am starting to think that these do not work together.

I have gotten conqueror maps from these other bosses. So I know that part is working, but I haven't got a Synth or shaper/guardian map either. And both of those specifically say "final map" vs Conqueror's "map boss" so I'm starting to wonder if this is just not really working as described or if I'm just having a really bad stretch of luck.

Another day of playing, and another day of not a single DP summoned boss procing The Most toys. So weird that a prerequisite node to get to DP doesn't interact with it.
