Hierplane visualization showing duplicate words

[cephcyn]

If I go to the dependency parsing demo https://demo.allennlp.org/dependency-parsing and enter "The quick red fox jumped over the lazy brown dog.", the output tree matches what I expect but the hierplane visualization shows "The quick red quick fox" as a branch off of "jumped" when it's minimized.

I'm unsure whether this is an issue in the demo code or this should be redirected to the hierplane library instead.

Unfortunately this is a known issue in hierplane. We'd like to fix it, but it's not a high priority for us. A good workaround would be to just add text output to the demo.
