Ionic live-reload does not work with CSS in the merges folder

/www/css/master.css which is empty
/merges/android/css/master.css which contains all styling.

When I deploy the app as usual, everything works fine. However, in live-reload the master.css is not applied. It just does not pick up all the styling in the merges folder.
When I copy the file from /merges to /www everything works fine. But that’s of course a hack, not a solution.

So, how to make live-reload work with CSS (and JS) in the merges folder?
