Reproduction steps:

1) Get DXP vanilla, patch it with de-8, start it, login as Admin
2) Create a user with

screen name: jonathan.bloggs
email: not relevant
first name: Thisisaverylongfirstname
last name: Andthisisaverylongsecondname

3) Add a Blog portlet on the page or a Wiki with something in the Front Page, so that comments are allowed
4) Type @t and observe how Thisisaverylongfirstname... appears

Expected:
First name (space) Last Name
(new line)
@screename

to appear. For example:

Thisisaverylongfirstname Andthisisaverylongsecondname
@jonathan.bloggs

Actual:

Thisisaverylongfirstname
Andthisisaverylongsecondname@

All in all, the main issue is that there is no space between the last name and the "@screenname" - this is appears to be the reason why the last name gets on the second line.
