Focus order through regions

Tab order should follow a predictable path.

Pattern

Modal pattern

Focus should move into the dialog on open, cycle inside, and return to the trigger on close. If focus escapes to the page behind, users can get lost.

Focus trap OKTrap broken

Dialogs and overlays

Move focus into modals on open and restore it on close.

Where this comes from on Next.js

Hydration timing: dialog opens before focus management runs; verify production build.

What this issue means

Fixes

On open, move focus to the dialog; on close, restore focus. Escape should close when appropriate.

How to fix on Next.js

In Next.js, verify both server and client components: hydration can change roles/names. Use `next/image` with meaningful `alt`, and ensure dynamic imports do not drop focus management.

How to fix

On open, send focus to the first interactive control; on close, restore focus to the trigger.

Support Escape where users expect dismissal; document exceptions.

Common mistakes on Next.js

Streaming suspending before focus effect runs—test full navigation.
Assuming dev overlay errors match production a11y tree.
Ignoring dynamic imports that shift structure.

How to verify the fix

Test the production build (focus and hydration differ from dev).
Verify both mobile and desktop layouts if they diverge.
Rerun the scan; compare rule counts on the same path.
