Grid-cell keyboard movement: End unexpectedly jumps to the last grid row · case 03
End unexpectedly jumps to the last grid row.
Case contract
Arrow keys move one cell and clamp without wrapping; Home/End target row edges; Control additionally targets the first/last row.
Why this case matters
A deterministic model of grid-cell keyboard movement; this isolates one interface invariant without requiring a browser.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
