// suppress release-based navigation during the wait, otherwise Left/Right would both
// turn the page AND fire the configured short action.
//
// In non-reader UIs (settings, file browser, etc.), only navigation reacts to release —
// the configured per-button actions are not dispatched there (see
// ActivityManager::dispatchButtonAction, which is reader-only). Gating on isShortPending
// there just makes Left/Right navigation feel sluggish (300ms lag) compared to Up/Down
