Dismiss Settings dialog is required for the Support page

[Julia Aranovich]

Go to the Support page, change statistics settings but do not save it. Then go to another page.

Expected result: Dismiss settings dialog appeared before user goes to another page.
Actual result: the next page is opened and statistics settings changes are lost.
