Wrong term pagination when altering the term query in custom taxonomy terms list

[opportus]

WP outputs the wrong term pagination if we alter the term query in custom taxonomy terms list with for example the list_terms_exclusions filter hook. In the screenshot below, we should have only 3 items in the pagination, but as you can see we get 21 items instead.

I believe the problem comes from this line:

​https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/class-wp-terms-list-table.php#L125

'total_items' => wp_count_terms( $this->screen->taxonomy, compact( 'search' ) ),

Shouldn't the pagination be defined based on the term query's result instead?
