+{-| Paragraph with children more than one level deep breaks flow
+
+<https://github.com/mdgriffith/elm-ui/issues/173>
+
+First of all, thanks for such a pleasant library to use! It's been awesome not having to use CSS.
+
+The problem I ran into is that paragraph only seems correctly flow text in children a single level deep. As an example, I made an Ellie demonstrating this with an el within a link within a paragraph:
+
+<https://ellie-app.com/7JcgLRNprF7a1>
+
+This might be a regression, as the resolved #50 and #103 seem to refer to the same problem.
+
+Expected behavior
+Text should flow with no breaks in the paragraph.
