+Subject: [PATCH] Fix SECTION headers in docstrings
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Make them coincide with the class names. The missing "Anaconda" prefix
+causes a build failure with gobject-introspection ≥ 1.61.1 due to [1]:
+
+    Namespace conflict: DocSection('BaseWindow')
+
+See https://bugzilla.redhat.com/show_bug.cgi?id=1885825 for some
+details.
