FileSystemDeploymentService: applications cannot be undeployed by removing .deployed marker

To undeploy an application using File System deployment, the application's associated .deployed marker needs to be removed. Once the .deployed marker is deleted, the application is stopped but then immediately readded/restarted without triggering it with a .dodeploy marker.

I've attached a .war to reproduce.
Copy servlet_js_servlet_web.war $JBOSS_HOME/standalone/deployments
touch servlet_js_servlet_web.war.dodeploy
rm servlet_js_servlet_web.war.deployed

The .war can never be undeployed.
