Steps to reproduce

1.Navigate to Connector field by pressing Tab key. 2.Press Tab key. 3.Observe the page.

UI elements

Actual Result

• List opens when Connector field is active and it stays on the page after user navigates to other elements.

Expected Result

• When another element is active, list for Connector field is not visible anymore (it is closed).

Notes When user clicks with mouse outside the field or press Esc key, list disappears - which is correct.
