In settings, clicking Search icon does not activate the cursor in the search field

Description

Visit Settings --> Privacy and Security--> Site and shield settings

When a user clicks the Search icon in Settings and begins to type, the cursor automatically jumps to the arrow next to Sites and Shields Settings instead of activating the search box.

This happens across all Settings options.

Steps to reproduce

1. Visit Settings --> Privacy and Security--> Site and shield settings
2. Click on the Search icon
3. Start typing
4. Observe the highlight 'arrow' next to the title. The search box cursor should be activated.

Actual result

Expected result

The search box field should be automatically activated when clicking the Search icon. Instead, it requires two clicks to begin typing in Search settings.
