Eclipse GWTPlugins - can't get the 'Sync the CodeServer running state with the WTP server' to work

I have a dynamic web project.
It has the GWT project facet and has the Sync flag ticked.
I have a Tomcat 7 based server that I stop and start from the 'Servers' view as usual.
It is configured for the module corresponding to the dynamic web project.
I have a code server launcher that is defined with its project set to the aforementioned web project.
The code server specifies the launcherDir as the deploy folder of the server app. ,and the server and code server work fine together - it's just that the stop and start of the server does not stop and start the code server, and that would be a nice thing to have working :).
Are there any other steps I have missed to tie the two things together properly?
This is all on Eclipse Neon by the way..... (and GWT 2.8.0 and the latest GWTPlugins as of 2 days ago)...

Reproduce the setup in Eclipse Neon with GWT 2.8.0, the GWT Eclipse plugin, a dynamic web project, and a Tomcat 7 server. Check the Sync setting and code server launcher behavior when the server is stopped and started; done means the code server follows the WTP server lifecycle.
