silver charm bug

silver charm activate when a slow is applied to you, the text implies, "used when you are affected by a slow".
If you are steping into chilling ground the charm activates and it negates the slows for the duration, but if the slow effect persist after the duration of the charm ended the expected behaviour would be for it to retrigger, but instead it doesn`t, you can still have charm charges available but you are slowed unless you re enter or have the slow source being re-applied.
Seems that what cause the charm to trigger is the application of the slow debuff source and not the state of being slowed.
Issue being that most sources of slow last more than 3 seconds so this makes the code of whever did this seem amateurish.

Just wondering if this is planned to be fixed? It appears that charms currently only activate when the condition is applied. If you gain sufficient charges while having the effect the charm does not activate.
