Fix smooth scroll and other bugs (#1861)

This PR fixes:

- The wrong clean up of window post message communicators
- The smooth scroll bug in chrome (Fixes Anchor navigation in render view not working #1770)
- Scroll by using touch devices in renderer
- Lazy loading of the editor (code mirror doesn't need to be lazy loaded any more)
