+From ff1a6be09b6856b34b30b00542a06819402094c6 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] fix test parameterization
+
+The patch for CVE-2025-68131 backported the tests in a way
+that inserted a new, not-parameterized test between another
+parameterized test and this test's parameters. Due to this
+the parameters were associated with the incorrect test, failing
+the execution.
+
+Fix that.
+
+Upstream-Status: Backport [https://github.com/agronholm/cbor2/commit/f1d701cd2c411ee40bb1fe383afe7f365f35abf0]
