SpringBoot Mongo connection ignores authenticationDatabase if database is set, but both are valid at the same time

I need a mongodb connection string like this:

spring.data.mongodb.uri=mongodb://localhost:27017/itr-devel?authSource=admin

I set these properties in the config expecting it to work:

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=itr-devel
spring.data.mongodb.username=root
spring.data.mongodb.password=Welcome^1
spring.data.mongodb.authentication-database=admin

The authentication-database is ignored if the database value is set.

With the above properties, I should get this URI: mongodb://localhost:27017/itr-devel?authSource=admin
