WooCommerce: Show only terms with products in stock

Question

I'm using get_terms to show a list of terms. It works fine so far. But I want to hide every term with out of stock products. If I use 'hide_empty' => true it wouldn't work because the products are there and published.

Is there a way to add the _stock meta field to the get_terms function? Unfortunately I have to use get_terms.

Here's my code (it's a lot bigger but that's the part):

$terms = get_terms( array(
    'taxonomy' => 'product_tax',
    'orderby' => 'name',
    'hide_empty' => true,
) );
