In catalog Category's assigned product grid, sort order is applied on entity_id as DESC by default like this:
But I want to apply sort order by default on position as ASC like this:
I found a file /vendor/magento/module-catalog/Block/Adminhtml/Category/Tab/Product.php

In this _construct, I set defaultSort as position, and it works but when I set defaultDirection as asc it cannot apply.
/**

protected function _construct()
{
parent::_construct();
$this->setId('catalog_category_products');
$this->setDefaultSort('position');
$this->setDefaultDirection('asc');

}
Please let me know if I'm doing any mistake.
Thanks in advance.
