'python-pytest-cov' is a wrapper for 'py.test'; it uses
'python-coverage' internally and only the later one contains the JS
code.

It only is a wrapper for 'pyhton-coverage', which is the real user.
(I did a `apt-get source python-pytest-cov`, which shows no direct
match, by it uses 'python-coverage' as a Build-Depends-Indep, so I
guesst it's pulled in that way.)

<https://codesearch.debian.net/search?q=[.]bind[%28][%22%27]key+filetype%3Ajabascript&perpkg=1>
shows more users and even users of the 'tzuryby' API, but they don't
seem to use your package but use their own packaging or it is some other
'bind' function not related to 'jquery-hotkeys' at all.

I think you can concentrate on those packages in Debian, which directly
depends on your package and just ignore the other hits of '.bind("key'.
