Issue Summary

Request Participant field only shows the first 20 results when searching for users.
This can make it impossible to add specific users if they are not one of the 20 users shown.

Steps to Reproduce

1. Add over 20 users with similar e-mail (eg. marcus.silveira@email.com, silveira.marcus@email.com, marcus.marcus@email.com) where at least 20 users with the similar email address is alphabetically before the desired user.
2. Search for exact e-mail (marcus.marcus@email.com) in Request Participant field

Expected Results

Only marcus.marcus@email.com shows up in the list

Actual Results

All similar users show up, possibly hiding the desired user if 20 users exist alphabetically before them.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
