Cannot assign issues to a user who is on the second page

Summary

As stated in the description and shown in the screencast below:

I can assign to "Jerome", but "Yohan" definitely exists but is not available in the list of assignees. The only difference is that Yohan is alphabetically the last of our 21 users.

Seen on 10.0.2-ee, may have existed on previously, but we just added are 21st user. Prefixing a couple of service accounts with z is a workaround, but only temporary.

Steps to reproduce

Have 21 users, try to assign an issue to the last user when alphabetically sorted. User's avatar flashes very briefly, but is not available for assignment.

What is the current bug behavior?

Unable to assign issues to certain users

What is the expected correct behavior?

Should be able to assign issues to any valid user irrespective of their name
