Glow does not goes away if unit loses aura being in stealth

[BannZay]

No SPELL_AURA_REMOVED is fired if unit being stealthed, Hence if unit pressed buff ability (lets say shadowstep) and then vanish, glow will not go away and cooldown is hidden until this ability is used again.

Steps to reproduce:

1. Face rogue on arena
2. Rogue casts Shadow Dance
3. Rogue casts Vanish while Shadow dances buff remains.
4. Rogue comes out of invisibility after shadow dance buff removed.

Expected:
Glow appears for the vanish duration and goes away after shadow dance expired.

Actual:
Glow is always active, icon does not shows cooldown until rogue casts Shadow dance again.
