+ *
+ * Scenario: after init at period 0, mark all initialized non-NULL tracks disabled and set
+ * their eos flags. Call HandleSeekEOSAndPeriodTransition with a non-negative remainingSeek.
+ * Expected (post-fix): no period transition occurs (returns false, period index unchanged).
+ * Pre-fix behaviour: the enabled check was absent, so eos on any non-NULL track drove
+ * a transition even if that track was not active.
