Level A · WCAG 2.1

2.5.2 Pointer Cancellation

A pointer action can be aborted: it completes on release, not on press, and moving away cancels it.

Manual only No automated check says anything useful.

How it fails in practice

A “delete account” button that fires on mousedown, so a slip of the hand is irreversible.

How to fix it

Act on click or on the up event. Anyone with a tremor depends on being able to slide off the control and let go safely.

How far an automated check gets

Nothing automatic decides this. A scanner that reports it as passing is reporting that it did not look. It stays untested until a person tests it and records what they did — which is exactly how we treat it: as untested, not as passed.
