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)...

在 Eclipse Neon 中使用 GWT 2.8.0、GWT Eclipse plugin、动态 Web 项目和 Tomcat 7 server 重现该设置。检查 server 停止和启动时 Sync 设置以及 code server launcher 的行为；当 code server 遵循 WTP server 的生命周期时即表示完成。
