Global $product changed

Hello!
In the file admin/class-enhanced-ajax-add-to-cart-wc-admin.php there’s a function display_variable_product_add_to_cart that uses global $product, then sets it’s value to a new product.
When the shortcode is used in another product’s single-product view, this changes the global $product unexpectedly. This has caused a conflict with another plugin to add custom product tabs (content taken from wrong product) and I imagine there could be any number of other conflicting plugins.
Since the variable doesn’t seem to require global status, I’ve removed it and the plugin is now working as expected.
