I have just updated to version 104, and when I create a new ticket and select multiple users in the input field cc_users_open, I am not able to see all the users I have selected. As a result, the users are listed outside of the input field.
This line of CSS from staff-desktop.css appears to be causing the issue:
.tickets-page .tickets .form_table .select2-container–default .select2-selection–multiple {
height: 32px !important;
}
