Selecting biscuits in inventory does not allow for quick purchase of additional potions [GAMEPLAY]

You can select an already purchased consumable in your inventory to bring it up in the right-hand part of the store interface. Normally, this acts as a shortcut to be able to purchase more of the same consumable, but seemingly because the ID of the biscuit does not correctly map to the potion that originated it, repeat purchases are disabled in the right-hand UI.

STR:

1. (In PVP.net) Put one point into the Culinary Master mastery
2. (In game) Open the store and purchase a potion(biscuit)
3. Left-click on the biscuit in your inventory to select it
4. Right-click on the biscuit's icon in the right-hand panel in an attempt to purchase more

Results: Nothing happens Expected: More potions(biscuits) are purchased

Notes: This has been bugging me ever since the mastery was introduced and the store UI was updated (been a very long time). For whatever reason I tend to use this UI path instead of the main left-hand interface to replenish a consumable I already have, and it's a pain to try and remember that it'll work with a ward or potion but not a biscuit.
