Firebrand Mantra + Dismount Bug

This one is a little subtle: Mantras that are on their last charge when you mount up will continue to regenerate their charges, but the ability stays as the final charge ability even past 1 charge and using the mantra will consume all charges.

To reproduce:

• Put a mantra on your bar
• Prepare it
• Use two charges so that the mantra is now on the final skill in the sequence
• Mount up
• Wait a sufficient amount of time for the mantra to recharge one or two charges.
• Dismount
• Confirm that the mantra is still on the final skill and has more than one charge
• Use it and confirm that all charges are consumed.

Here's a screenshot of my bar showing the phenomenon:https://i.imgur.com/hWCAQe9.png

This has killed me at least twice due to not having my stunbreak or heal charges. :P
