When there is no title, it struggles to do this and transforms the tree inproperly. Depending on the rST used, this may result in an assertion error deep in the docutils HTMLWriter. (Observed when using ".. admonition:: Notes" under such a section - When this is transformed with its own element, Sphinx is fooled into believing this title belongs to the section and incorrect mutates the docutils tree, leading to errors during rendering time.) When parsing an untagged section (free paragraphs), skip making a hollow section and instead append the parse results to the prior section. Many Bothans died to bring us this information.
