getContext() returns undefined when accessing another block's context

[jamesina2]

Great job on Interactivity API so far!

I'm trying a proof of concept where I can access another block's context. I initialize two blocks with:

npx @wordpress/create-block@latest block-1 --template @wordpress/create-block-interactive-template
npx @wordpress/create-block@latest block-2 --template @wordpress/create-block-interactive-template

I give their stores different names and try basic functions for each, everything is working fine there.

However, when I try to access block-1 context from block-2 eg. const anotherBlockContext = getContext('block-1') I get always undefined

My block-2 view.js example:

store( 'block-2', {
	actions: {
		toggle: () => {
			const context = getContext();
			console.log(context); // works 
			const anotherContext = getContext('block-1');
			console.log(anotherContext); // undefined
			context.isOpen = ! context.isOpen;
		},
	}
} );

Any particular reason why this would return undefined?
