Closing as this is really a [HiGlass](https://github.com/higlass/higlass) issue, but it looks like the color bar in the first example is thresholded at 1 so the pixels with value

> We definitely want to see multi language support (cc: @manzt) Awesome. Yah, something that should be very possible with zarrita.js.

Sorry I've been out of the kerchunk loop for a bit but I've been trying to stay abreast of changes. zarrita.js has an HTTP-based reference store (and will try to...

is ipython still a required dep with `comm`? / would it be possible to dynamically import and call to `get_ipython()`, only when necessary?

Interesting. This is certainly related to replacing `JSON.parse(JSON.stringify(obj))` with `structuredClone(obj)`. However, I'm almost certain that previously whatever is causing this issue would just be silently deleted from the cloned object....

I think you should be able to fix this in ipytree by implementing a `serialize` to complement the `deserialize` for `selected_nodes` trait, overriding the automatic `deepcopy` serialization: https://github.com/jupyter-widgets/ipywidgets/blob/93a848b5ad541db08f464a22b15d05abcfe03a63/packages/base/src/widget.ts#L526-L548 ```javascript TreeModel.serializers...

I think it is extremely unlikely that every downstream package will need an update due to this change (elaborated below), but I certainly see your point. Perhaps just make the...

Thanks for the PR! Looking into this deeper, I think `pack_models` was implicit with `JSON.stringify(JSON.parse())` because each model instance implements `toJSON()`: ```javascript JSON.stringify([ { toJSON: () => "FOO" }, {...

The assumption of `toJSON` why was it worked previously to forgo a custom serializer with objects containing `WidgetModel`s, but I understand the want to mirror `unpack_models` and make it more...
