S3binary field for many languages holds only binary data of the latest language saved

Problem

S3binary objects are saved to the configured S3 bucket in the mesh server. Everything is working as expected for the default language, but once I start adding binaries for the second language, the binary data is overrwiting the existing binary information.
In the end, it results a combination between corect metadata for a language, combined with the binary data from the latest language binary saved in that s3binary field.
I noticed also that for all languages there is only one single s3binaryuuid created for a s3binary field. I believe it should be different for any language, similar to the binary field.
