"format.splitAttributes:true" adds excessive indentation

Having "format.splitAttributes:true", given:

<?xml version="1.0" encoding="UTF-8"?>
<beans
        xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:camel="http://camel.apache.org/schema/spring"
        xmlns:util="http://www.springframework.org/schema/util"
        xsi:schemaLocation="http://www.springframework.org/schema/beans 
          http://www.springframework.org/schema/beans/spring-beans-4.2.xsd  
          http://camel.apache.org/schema/spring 
          http://camel.apache.org/schema/spring/camel-spring.xsd
          http://www.springframework.org/schema/util 
          http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <!-- Add routes here -->
        <route>
            <proces|// complete here
        </route>
    </camelContext>
</beans>

results in weirdly formatted xml, with too many indentations:
