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%.

Another example:

https://akarnokd.github.io/rng-76/chances.html?patch=P20&nocoalesce&formids=002C5DEB-003D7F7F-0011A36A

• LLV_Vendor_Armor_Faction_Responders x 6 (100%)
  • LL_Armor_Underarmor_Generic (33% by the list itself), (1 - (1 - 1/3)^6) = 0.912208
    • Armor_RaiderMod_Underarmor_LongJohns "Mk5" (20% by the entry itself), should be around 33.9%

This last should calculate as 1 - (1 - 1/3 * 1/5)^6 = 33.8907
