/**
 * Regression test for `browse fill` on change-only validators.
 *
 * Playwright's Locator.fill() dispatches an `input` event but not `change`.
 * Frameworks that validate on `change` (AngularJS ng-change, debounced
 * strength/match checks — e.g. cPanel's Jupiter theme "Add FTP Account"
 * password-match check) never see the update: the DOM value is correct but
 * the framework's own validator still reports a mismatch.
