/**
 * Tests for the new "Manage Exceptions…" button added by Bug 1767271.
 * Only the patch-specific concerns are covered here:
 *   1. The button is rendered in custom history mode.
 *   2. Its enabled state follows the privacy.sanitize.sanitizeOnShutdown pref.
 *   3. Clicking it opens the permissions sub-dialog wired for
 *      "persist-data-on-shutdown" (not e.g. cookie exceptions).
 *
 * Generic permissions-dialog behaviour (add/save/cancel/remove) is owned by
 * the existing tests under preferences/tests/etp/.
