+
+Previously, certain elements received an additional newline when indented due to the title not being correctly recognized as a block by the DOM Parser serializer. This caused unwanted whitespace to appear in the output. The issue was resolved by explicitly marking the title as a block within the code, ensuring that serialization no longer introduces unnecessary whitespace.
