[Ohrimenko1988]

Description

We have unexpected fail of CheckErrorsWarningsTabTest in the selenium tests, it looks like something went wrong with a method which does click to the item in the "Preferences" form. We need to investigate and fix this problem. **Log:** ``` org.openqa.selenium.ElementNotVisibleException: element not visible (Session info: chrome=56.0.2924.87) (Driver info: chromedriver=2.27.440175
