Comment:

 Testing notes:

 1) Install classic-editor
 2) Create around one thousand tags: `wp term generate post_tag
 --count=1111` (Tag 1, Tag 2, ... Tag n)
 3) Go to the classic editor interface
 4) Search for the term `tag` in the tag search

 **Before**
 * impractically large search results dropdown
 * I wasn't able to make it crash (even after adding another 5111 tags) but
 the AJAX request was slow

 **After**
 * Tags limited to a usable amount
 * AJAX request faster
 * `number` parameter confirmed to have an affect
