Feature: Background scrolling behavior in mobile search overlay
Scenario: Search overlay restricts background scroll
Given I am using the mobile site with the new search experience
When I tap the search icon and the search overlay opens
Then only the search results area should be scrollable
And the page content behind the overlay should not scroll
And there should only be one search bar visible
```
