Updating the sbt version to 1.3.7 prevented Intellij from successfully retrieving the source.jars for ScalaJS libraries. The project was unaffected, but this interfered with the editor's autocomplete. As a short term fix, these libraries were excluded, but importing the project into Intellij without retrieving the sources has solved the issue.
