Comment (by pikamander2):

 @SergeyBiryukov - I've attached a patch that:

 1. Adds support for specifying the number of terms to be returned (the
 default remains unlimited like before for the sake of backwards
 compatibility) in the wp_ajax_ajax_tag_search function in ajax-actions.php

 2. Sets the relevant GET variable to 20 in the Classic Editor's AJAX call
 in tags-suggest.js to match the Gutenberg behavior and prevent browser
 crashes on sites that have thousands of tags
