Warding Totem Does Not Show Charge Progress

This is something that's bothered me for a good long while now. The Warding Totem trinket generates charges to place a temporary ward. However, when you already have a charge, the HUD gives you no indication when the next charge will be ready. There's no "cooldown" animation like when you're charging the first ward, and there's not a timer displaying the time until the next charge either.

Does anyone else think there should be an indicator of the second charge's progress? I've searched for threads with the same complaint and was only able to find this reddit thread.
