-* Fix: reference links in html to md conversion use the same ref when link text is the same. Now
-  the reference id will be generated by adding `_xxx` suffix, where `xxx` is an increasing
-  integer, starting at 1, and incremented until a unique reference id is generated.
+* Fix: reference links in html to md conversion use the same ref id when link text is the same,
+  even when the URLs differ. Now the reference id will be generated by adding `_xxx` suffix,
+  where `xxx` is an increasing integer, starting at 1, and incremented until a unique reference
+  id is generated.
   * Add: `UNIQUE_LINK_REF_ID_GENERATOR`, default `(refId, index) -> String.format("%s_%d",
     refId, index)`, a `BiFunction<String, Integer, String>` taking refId string and integer
     index and returning a string for the "uniquified" ref id to use for a reference link.
