…45202) There is a bug in the dense_vector field mapper where default index options will be set to null when the element type is BFLOAT16. This PR fixes that by handling BFLOAT16 as equivalent to FLOAT and adding a default index options test. (cherry picked from commit d807c64) # Conflicts: # server/src/main/java/org/elasticsearch/index/IndexVersions.java # server/src/main/java/org/elasticsearch/inference/SimilarityMeasure.java
