About track->"Copy config" includes baseUri entries on UriLocation objects

[cmdcolin]

I feel like this should be filtered out

[cmdcolin]

This is actually an oddly deep problem. There is code here for example that 'looks like it is filtering out baseUri'

jbrowse-components/packages/core/util/types/mst.ts

Lines 74 to 80 in 93ab92d

	postProcessor: snap => {
	// xref https://github.com/mobxjs/mobx-state-tree/issues/1524 for Omit
	const { baseUri, ...rest } = snap as Omit<typeof snap, symbol>
	if (!baseUri) {
	return rest
	}
	return snap

but actually it just filters out undefined baseUri

And, it is not valid to change it to filter out baseUri there because it is needed after RPC serialize/deserialize

Alternative approaches could be attaching e.g. baseUri to the "mst environment" or something like this, but it may be challenging

initial assessment from pairing with @garrettjstevens yesterday :)

the way that this works at the level of the jbrowse config is here

jbrowse-components/products/jbrowse-web/src/jbrowseModel.ts

Lines 30 to 35 in fcb7dc8

	{
	// eslint-disable-next-line @typescript-eslint/no-explicit-any
	postProcessor(snapshot: Record<string, any>) {
	return removeAttr(clone(snapshot), 'baseUri')
	},
	},
