Nested foreach entries calculate probabilities incorrectly

Example: https://akarnokd.github.io/rng-76/chances.html?patch=P20&nocoalesce&formids=002C5DEB-003D7F95-0033AB36


```
☢ WEAP:0008E736 <BaseballBat> "Simple" | 4.167% | 15.596%
```

The parent says `LLV_Vendor_Weapon_Melee_Faction_Responders`  x 4, the child `LL_Weapon_Melee_BaseballBat` calculates 15.654% because of the power rule, but the child still uses the flat 4.167%.
