+ * Whether a paragraph's only inline leaf content is break placeholders

+ * Distinct from `isVisuallyEmptyParagraph`, which returns false when any
+ * break node is present. This predicate catches the complementary case:
+ * paragraphs that *look* empty to the user but technically contain a break.
+ *
+ * Context: after splitting a list item that ends with a trailing `w:br`,
+ * the new paragraph inherits that break. In WebKit the resulting DOM shape
+ * causes native text insertion to land in the list-marker element
+ * (`contenteditable="false"`) instead of the content area — and
+ * `ParagraphNodeView.ignoreMutation` silently drops it. Detecting
+ * this shape lets the `beforeinput` handler insert via ProseMirror
+ * transaction instead of relying on native DOM insertion.
