Righteous Fire/Eternal Youth/Coruscating Elixir bug

When buffed with righteous fire and having the eternal youth selected, if you have the flask modifier "used when you hit a rare or unique enemy" on Coruscating Elixir, it is turning off righteous fire even though you are not taking life damage to reset the life recharge. I Swapped the modifier to "reused at the end of this fask's effect" and does not turn off righteous fire. I haven't tested other flask modifiers on Coruscating Elixir.
