Hi @martaszmit, yes, that makes sense. I believe the relevant changes would be in [`SplitPanel.handleEvent`](https://github.com/jupyterlab/lumino/blob/705ffa941ecc1b46d9cbf8abd1d1de9428770eed/packages/widgets/src/splitpanel.ts#L159).

What is the output of `node --version`?

Hmm, I just tried in a fresh environment with `node v14.17.4` and `yarn 1.22.17` on my macOS 11.6 and it built fine. What version of yarn and which OS are...

I also tried with Wndows 10 Pro and it built fine, we're also building against Windows in CI. I've not seen an error like that before, I'm not sure what...

Ha, node is definitely like that sometimes...

I'm not able to view the video. Can you please push your work in progress to a pull request? We can look at the code together, and the changes will...

What a nice world it would be if everyone followed the spec :smile:

I had noticed the same even after trusting the html, which is why we switched from binder to static html on ReadTheDocs in #241

Right, binder isn't compatible with hosting our examples

Let's merge and...iterate.
