Roving tabindex navigation: Horizontal arrow direction ignores right-to-left layout · case 03

Horizontal arrow direction ignores right-to-left layout.

Member previewVariant 3 · 3 implementations · 11 checks per implementation

Case contract

Home and End select enabled endpoints; horizontal arrows honor directionality and wrap; a removed current item resets to the first enabled item.

Why this case matters

A deterministic model of roving tabindex navigation; this isolates one interface invariant without requiring a browser.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
