Multiplatform "gradle run --continuous" not reloading js

If i create a mutiplatform project (File → New Project → Full-Stack Web Application) and choose the React Application template, I get a working webapp. I can execute “gradle run” and it will start up the react webapp no problems.

However, i cannot work out how to get continuous / js reload working. I’ve tried “gradle run --continuous” and it doesn’t work.

Am I missing something? Can someone help me out, running the app each time means I have a 1min+ startup each time. is the multi-platform template broken?
