Cannot select an author from dropdown due to truncated users list

[yanksyoon]

Hello team!

Currently, when we have over 50 users with same email signatures, e.g. over 50 users with email @zemail.com (with usernames starting with characters preceding z), and there is a user with username zemail, the user zemail can never appear in the dropdown since the request made by the dropdown
http://<wordpress-link>/index.php?rest_route=%2Fwp%2Fv2%2Fusers&context=view&who=authors&per_page=50&_fields=id%2Cname&search=zemail&_locale=user is sorted alphabetically.

This makes it impossible for the user to be selected as an author of a new post.
Would the search be better limited to usernames?

Searching for the user "amailer" shows no matching results.

Here's the payload for the search request on the dropdown. As you can see, the user amailer is truncated.

Request URL: http://10.1.190.162/index.php?rest_route=%2Fwp%2Fv2%2Fusers&context=view&who=authors&per_page=50&_fields=id%2Cname&search=amailer&_locale=user

The script to generate random users:

---
#!/bin/bash

# Function to generate a random username beginning with 'ab'
generate_username() {
  local username
  username="ab"

  # Generate a random string of characters
  random_string=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 8 | head -n 1)

  # Append the random string to the username
  username+="${random_string}"

  echo "$username"
}

# Iterate to create 50 users
for ((i=1; i<=50; i++)); do
  # Generate a random username
  random_username=$(generate_username)

  # Create WordPress user
  wp --allow-root user create "$random_username" "$random_username@amailer.com" --role=author

  echo "Created user: $random_username"
done
---

Then, generate the target user:
wp --allow-root user create amailer amailer@amailer.com --role=author

Goto create post.
Select author dropdown on the right panel.
Search for amailer user.
The user is not found in the dropdown.
