Required permission to see stuff in "10 newest unowned tickets" area


I use 3.4.5 RT and I’m having hard time figuring out how to let user
see unowned tickets from the queues he has access to in “10 newest
unowned tickets” area.

He has all but admin* rights assigned to him for specific queues and
if he clicks on a queue name in “Quick search” section, he sees and
can take/delete unowned tickets from the search results page. However
it won’t show him unowned tickets on the home page, until I grant him
"show ticket" rights globaly. Am I missing something or is it the way
it’s suppose to be “by design”?
