This is a minor regression, but it comes up every now and then in joint debugging sessions.

In previous versions, till v 3.0, of Zabbix, global search field contained the search phrase after searching. Starting from 3.0, that field is cleared.
This is inconvenient when one notices that they made a typo in the search string, or the search results indicate that the search string needs to be amended for some other reason.
Continuing requires copy-pasting the string, retyping it or going back in the browser history.

Please consider fixing this regression and not clearing the search field.

Note that no other frequently used tool or site clears user input for search - even if this behavior was lifted from Jira, it is not comparable, as Jira actually puts search terms in the dedicated search field for user to modify if needed.
