Lots of bugs in shop when calculating regen and lifesteal

I see this all over the shop when stacking regen and lifesteal. I never know where I am with the numbers because the calculations go sideways pretty quickly.

Looks like it's an interaction with the Healing Booster item rather than lifesteal. Only seems to affect those Extra/Improved/Boundless Spirit items.

It does seem to be an interaction with healing booster, but does also seem to affect things that are not an extra/ improved item. Here it is when calculating lifesteal.

I was encountering this when trying an Abrams build.

Spirit Lifesteal is still reading properly (23% -> 29%)
Leech with Healing Booster should be reading
(29% -> 70%)
but is currently reading
(23% -> 41%)
