Bug regarding types in az storage entity?

Question

We have problems using Azure CLI to update a storage table (non-Cosmos). A string like "2021.4" will be converted to a Double and there seems to be no way to avoid that.
I have looked here: https://stackoverflow.com/questions/46834171/how-do-i-specify-the-field-types-when-using-the-azure-cli-entity-insert-command
but passing odata.type=Edm.String causes the call to fail in this case.

See the following commands:

az storage entity merge (account, table etc) --table-name Products --entity PartitionKey=”fisken” RowKey=”” DisplayVersion=”Fisk”

-> Success, data type is String

az storage entity merge (…) --entity PartitionKey=”fisken” RowKey=”” DisplayVersion=”2021”

-> Success, data type is Int64

az storage entity merge (…) --entity PartitionKey=”fisken” RowKey=”” **DisplayVersion=”2021” ****@odata.type=Edm.String

-> Success, data type is String

az storage entity merge (…) --entity PartitionKey=”fisken” RowKey=”” DisplayVersion=”2021.4”

-> Success, data type is Double

az storage entity merge (…) --entity PartitionKey=”fisken” RowKey=”” **DisplayVersion=”2021.4” ****@odata.type=Edm.String

-> ERROR!

Client-Request-ID=(...)

Surely this must be a bug?
