I don't think it's a good idea to replace the entire css. For now, i'm fixing this within my app custom style using the code below:

.jstree-proton .jstree-clicked {
  color: inherit;
}

A proper fix should be done and merged in a new version of this package. Any contributor have suggestions? (@vedraan , @tihomiro , @brunowego)
