Describe the bug
The delay in loading during a player login event or reload may cause the "stealth state" icon not to show properly where the player is initially in stealth state. This bug affects druid 'Prowl' and rogue 'Stealth' states.

Background
When a user logs into the game for the first time and is in a stealthed state, the icons should display the "stealthed" version of the icon.

The fix to this issue is to perform the "stealth state" icon update during a PLAYER_ENTERING_WORLD event, i.e. when the player logs in for the first time (does not affect reloads).
