Description
The user should not be able to select an item and then search for another item. This behavior may lead to a big cognitive load for the user who might not remember exactly which items are currently selected after several iterations.

This behavior is reproducible only in 7.0.x due to the fact that in master the search field is moved to the secondary navbar. When a user selects an item in master, the search field is removed and so not able to reproduce.

Steps to reproduce
1. Content > Web Content and create two web contents with title 'aaa' and 'bbb'
2. Select web content 'aaa' and search for web content 'bbb'

Actual result: The search will bring up web content 'bbb' with 1 item selected.
Expected result: The search bar and search buttons should be disabled.
