Problem/Motivation
The issue https://www.drupal.org/node/2395853 for some small mistake ended up introducing a "bug", the css file tree-child.module.css turned out to be referenced in the library file erroneously, i do not think it's worth reverse the related issue to solve it
Proposed resolution
according https://www.drupal.org/node/2395853#comment-10148318 the file name should be tree-child.module.css
the patch fix this :)
