POE 2 "Iron Reflexes" keystone not applying full value to Evasion stat when modifiers are in use

Currently, the aforementioned keystone only converts the raw Evasion stat value on equipped gear, and ignores passive skills, support gems, spirit gems, and other attributes that modify said stat further.

For example, if I had a raw Evasion value of 2950, and had equipped the Wind Dancer spirit gem that gave me 16% increased Evasion Rating per stage, up to a total of 3 stages amounting to 48%, and the Catlike Agility passive skill for a 25% increased value after a dodge roll on top of that, I get an in-game total sum of 4682 Evasion; however, upon testing the Iron Reflexes keystone I found that the game only converts the aforementioned raw stat of 2950 Evasion found on my gear into 2950 Armor, ignoring all modifiers that SHOULD otherwise provide the full 4682 Armor. If this is not a bug, then the passive skill tree description of the item should state that the keystone does not take modifiers into account, because, and I quote:

"

Converts all Evasion Rating to Armour

is the description for the keystone, and 2950 is not "all" but only a limited fraction.
