Why are empty directories like https://github.com/w3c/web-platform-tests/tree/master/html/syntax/named-character-references still in the repository? It looks like the test files have moved to https://github.com/w3c/web-platform-tests/tree/master/html/syntax/parsing. Just wondering.
