What steps will reproduce the problem?
1. Open a fight using any shock spell outside of melee range
2. The shock bar will show up for an instant then disappear (well before cooldown is up)
3. Subsequent shock casts will show up normally

What is the expected output? What do you see instead?
I would expect the shock bar to stay up until the cooldown is over.  Instead, the shock bar disappears almost instantly.

What version of the product are you using?
v6.20 (r373)

Do you have an error log of what happened?
No

Please provide any additional information below.
There is a very specific circumstance that causes the shock bar to disappear before the cooldown is up. 1. A shock must be used as the opening spell to enter combat.  If you use another ranged cast to open the fight followed by a shock the shock bar works fine.  The shock must be cast outside of melee range.  If it is used as an opener inside of melee range the bar will work normally.  This is easily repeatable and happens every time the two conditions above are met.  On subsequent casts of a shock spell during the fight the bar will work fine, it is only the initial cast that disappears.
