Hierarchical drag hover expansion timer: User expansion is misclassified as hover-owned · case 04
User expansion is misclassified as hover-owned produces the wrong hierarchical widget state in a regression fixture.
Case contract
Hover expansion processing occurs only after dwell on a legal branch. Already user-open branches must not acquire hover ownership. Leaving or changing target resets the timer. A drag generation prevents old timers expanding a later drag. Auto-opened branches close on cancelled drag but user-open branches remain.
Why this case matters
Offline executable model of a hierarchical accessibility interaction; inputs are bounded and valid as stipulated. No browser, assistive technology, or normative ARIA conformance is claimed.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| user opened | [["a", "b", "r"], ["a", "b"], null, true] | [["a", "b", "r"], ["a"], null, true] | Failed |
