[1.2.2] Blood Splash interfering with arcane shield

[EPluribusUnum]

When my healing spell crits. the message logs says I hit myself "for 11 healing, 1092 healing (0 total damage) [1103 healing]."
The 11 healing clearly comes from blood splash rank 1 and the 1092 comes from my spell (arcane reconstruction). However, with arcane shield on, I should get a shield of around 500 dmg (its at 47% right now for me) but I only received a a shield of 7 (value is boosted due to the talent shielding). This leads me to conclude that that arcane shield is only calculating from the 11 healing due to blood splash and not the total amount.
