Muramana visual bug after death

If you die with the (Muramana) Active, you will spawn with the visual effect+mana drain+bonus ad, however both the item and the toolbar will show it as inactive. If you then (de)activate Muramana, it will return to the proper de-active state of no visual, no toolbar effect, and the active isn't, well, active.

I can reproduce this with 100% consistency by dieing with the active up.
