I don't see this bug over at Imviz. Alas, I am unable to build this PR from source on Debian + WSL2 (it got stuck at yarn install forever), so I'll just have to trust you on this one... Or maybe other Jdaviz devs can vet this instead.

I was also unable to reproduce the bug on release bqplot in Jdaviz, but I'm willing to trust that this line is useful. I was also getting errors trying to pip install the dev version, not sure what's up:

ValueError: missing files: ['share/jupyter/nbextensions/bqplot/index.js', 'share/jupyter/labextensions/bqplot/package.json']

@rosteen , I got those too but they went away (to be replaced by a different problem) after I installed yarn.

I suspected that would be the case, I was being lazy and didn't want to muck about with yarn...

Re: yarn -- Indeed, if you muck around too much, you might get tangled. 😏

Well, I can confirm this didn't break anything in Jdaviz at least.
