Setup button

Actual Result

• There is no focus on any element so cannot understand which element should be active.

Expected Result

• After x (close) button, Setup button should get focus visible.

Notes:
When user is on X (close) button and presses Tab key, he/she can press either Enter or Space bar key - nothing happens.
Only after pressing Tab key one more time, focus is visible on Setup button.

Same behavior observed on

• Indices page with Default settings dialog. When on x (close) button user presses Tab key - no focus visible on ingest pipelines link. It appears on the link, when user one more time presses Tab key.
