 ::::{dropdown} Prevent LIMIT + MV_EXPAND before remote ENRICH
 Queries using LIMIT followed by MV_EXPAND before a remote ENRICH can produce incorrect results due to distributed execution semantics.
 These queries are now unsupported and produce an error. Example:
-[source,yaml]
-----------------------------
+
+```yaml
 FROM *:events | SORT @timestamp | LIMIT 2 | MV_EXPAND ip | ENRICH _remote:clientip_policy ON ip
-----------------------------
+```
+
 To avoid this error, reorder your query, for example by moving ENRICH earlier in the pipeline.
