When I want to search specyfic ticket number then always popups a list of users/client emails

I think that when somebody want to search specyfic ticket number and starting typing with hash sign then the list should not appear.

IMHO:
Current behavior is confuse feature because mostly in such cases I just want to enter ticket number and press ENTER key, but mostly the email is taking focus and in a effect I osTicket engine is searching all tickets for this email.

Question:
Could this be disabled ?
