From the screenshot below, you can see that bullet lifesteal is not properly calculated when Healing Tempo is bought. In the screenshot you can see that originally it was 40% and then when Healing Tempo is bought it will go to 43% (Can also be seen in screenshot that bullet lifesteal granted is 43% when activated via the side bar). Healing Tempo state that it grants 25% Healing Effectiveness so if it was working properly, the bullet lifesteal should go to 50% (40 + .25(40) -> 40 + 10 -> 50%).
As a side note, Healing Tempo seems to work on her properly on Stone Form (19% is rounded to 20% and add .25(20) = 5 we reach 25% which is close to 24%). This bug is easy to replicate by buying Boundless Spirit and Healing Tempo and verifying yourself.
