Ionic serve: File(s) changes not reflected in the browser, slows down development

Ionic serve isn't serving the latest changes after saving a file. It's kind of a deal breaker during/for development. I am often forced to save a file at least once or restart ionic serve in order to work around this annoying issue.

**Steps to reproduce:**
1. Unpack https://drive.google.com/file/d/0B4eB_Qz7OSaTVndrVC1TdlliSkE/view?usp=sharing
2. Yarn (or npm install)
3. ionic serve
4. Make some small edit in src/components/bar/bar.html

The same issue is present even when using ionic CLI 2.2.3
