Steps to reproduce

• Go to the 'All articles view' or an individual reading list with at least 1 saved article
• Tap on the search bar

Expected results

• User can exit search without having to navigate to an article or to a different tab or searching

Actual results
There is no way to close search without taking another action

Proposed solution

• When the search focus state is active replace the 'Sort' link with 'Cancel'
• Tapping on 'Cancel' exits the search focus state
