A web app that runs with spring.main.web-application-type=none should start up and doesn't

Sample application can be found here:
https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-flyway

Steps to reproduce:

• Add spring.main.web-application-type=none to application properties: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-samples/spring-boot-sample-flyway/src/main/resources/application.properties
• Add CREATE SEQUENCE hibernate_sequence; to V1__init.sql (probably because of this issue: set spring.jpa.properties.hibernate.id.new_generator_mappings=true by default #7612)
• Run the application

It fails to start because of:

Caused by: java.lang.IllegalStateException:
WebApplicationObjectSupport instance [ResourceHttpRequestHandler [locations=[class path resource [META-INF/resources/webjars/]], resolvers=[org.springframework.web.servlet.resource.PathResourceResolver@12d40609]]]
does not run in a WebApplicationContext but in: org.springframework.context.annotation.AnnotationConfigApplicationContext@27ae2fd0:
