+Fix `[object Object]` in ChangeHistory aria-label and dropdown horizontal scrollbar
+
+- Change history labels were passing a JSX AST object instead of a plain text
+  string to the `ChangeHistory` component, causing `aria-label` to render as
+  `[object Object]`. Labels are now extracted as plain text via `remark-parse`.
+- The ChangeHistory dropdown could show a horizontal scrollbar when label text
+  overflowed the fixed-width container. Added `overflow-wrap` and `word-break`
+  rules to prevent this.
