JetBrains HTML Live Edit (remote debugging) doesn't work (at least properly)

I run "Debug index.html". JetBrains Intellij IDEA 2016.3 successfully connects to JetBrains IDE Support 2.0.9 on top of Chrome 57.0. The browser says "JetBrains IDE Support is debugging this browser."

But when I add something in html page in the Intellij (say <h1>test</h1>) my page remains unchanged in the chrome. Actually when I press 'rerun debug' in IDE or 'refresh' in the browser the changes applies, but as far as I know it's not supposed to work like that!

What can I try to make HTML pages reloads automatically?
