PoE 2 Visual Timer Bug

The skill support gem "Hourglass" is one that puts a 10 second timer on something that doesn't already have a cooldown to do 40% more damage, however on mercenary, switching to a bolt activates the UI of the timer while not actually activating it, so you can shoot the shot but the timer animation is completely desynced.

Edit: Upon further examination this fake timer also locks you from reloading your bolts and switching to the skill if you switch off of it.
