It looks that this PR fixes issue from #21499, but it breaks another use case:

1. Add any product to cart
2. Navigate to the cart
3. Un-hide "Clear Shopping Cart" button which is hidden in Luma by default by running this in browser console:
   jQuery("#empty_cart_button").show();
4. Use Tab key to focus Clear Shopping Cart button
5. Press "Enter"

Now the only way to trigger Clear Shopping Cart button is to click it with mouse, it's not possible to submit this action using keyboard anymore.

Hi I am sorry but I am not a programmer. But how do we achieve this? Where do we add the " jQuery("#empty_cart_button").show();"?
