Cart form default action is to empty cart

[aario]

Preconditions (*)

1. Magento 2.3.1
2. Firefox, Chrome, Safari

Steps to reproduce (*)

1. Add a product to cart
2. Go to cart page
3. Edit the quantity
4. Press enter inside quantity input box

Expected result (*)

1. Quantity must be updated

Actual result (*)

1. Cart gets empty

More info:

It happens in:
vendor/magento/module-checkout/view/frontend/templates/cart/form.phtml
Where there are two submit buttons in a form:

        <button type="submit"
                name="update_cart_action"
                data-cart-empty=""
                value="empty_cart"
                title="<?= $block->escapeHtml(__('Clear Shopping Cart')) ?>"
                class="action clear" id="empty_cart_button">
            <span><?= /* @escapeNotVerified */ __('Clear Shopping Cart') ?></span>
        </button>
        <button type="submit"
                name="update_cart_action"
                data-cart-item-update=""
                value="update_qty"
                title="<?= $block->escapeHtml(__('Update Shopping Cart')) ?>"
                class="action update">
            <span><?= /* @escapeNotVerified */ __('Update Shopping Cart') ?></span>
        </button>

When the Enter key is pressed inside quantity input box, the browser automatically chooses the first submit button which is to empty_cart. Order of these buttons should be reversed or a javascript added to define the default behavior when Enter key is pressed.
