Laravel pagination won't re-initialize MySQL variables

If I have this query:
select
id,
@product_rank := IF(@current_category = category_id, @product_rank + 1, 1) AS product_rank,
@current_category := category_id
from products
And create a query using Eloquent builder:
Products::from(DB::raw('
(select
id,
@product_rank := IF(@current_category = category_id, @product_rank + 1, 1) AS product_rank,
@current_category := category_id
from products) as q
'))->where('product_rank', '<=', 10)->paginate(5);
Because Laravel pagination wants to get the total count of all records, it executes an extra query like this:
select count(*) as aggregate from (
select
id,
@product_rank := IF(@current_category = category_id, @product_rank + 1, 1) AS product_rank,
@current_category := category_id
from products
) q where product_rank <= 10
So @current_category
and @product_rank
won't re-initialize and the main query returns wrong results.
I wonder if there is way to re-initialize both variables.
