Shopping Cart - update quantity doesn't update tax

On the shopping cart page, when the quantity is updated, the item total price and order total dynamically update, but tax does not.

What would the data-th be? data-th=“TaxPrice” or data-th=“Tax”

Is there an update cart button?

If I refresh the page, the tax then updates to the new amount, but not dynamically.

Is this a configuration issue or a bug?

Solved.
Works now with using the Html variable rather than {{item.taxPrice}}:

{{item.taxPriceHtml}}
