On_use trigger time changes when Chargeable is added

When the chargeable component is added to an item, the trigger time of the on_use component will change state depending on if the player holds the use button for the entire use_duration.

Set-up:
Add on_use that triggers an event, chargeable that triggers a second, and use_duration to an item.

Expected result:
on_use will trigger as soon as the item is used.
chargeable will trigger after the use duration.

Observed result:
If the player uses the item for the full use duration the on_use will trigger at the end of the use_duration. 
If the player clicks the use button, on_use will trigger immediately.
chargeable does not trigger
