Link click handling breaks the <Router> isolation/context principle

Riproduci il problema nel CodeSandbox collegato con due istanze di Router, quindi esamina la gestione dei clic a livello di documento del componente A e il percorso di contesto/integrazione di Router. Conferma che i clic all'interno di ciascun Router chiamino il setter di integrazione di quel Router e verifica il comportamento rispetto ai passaggi di riproduzione elencati.

Describe the bug

I'm making the assumption here that this package supports multiple routers running at the same time as it does use context for isolation instead of some kind of global store. Described bug is not an issue if my assumption is wrong.

Router component provides context which isolates and enforces the scope of router functionality.
For example useLocation under <Router> returns the location for that particular router.

Link click handling (A component) breaks that principle and functionality because link click event handler is added to document and if you have multiple routers (with default integration or custom), only one integration setter will be always called.

I propose to handle it in some sort of scoped way, for example:
<Router scopeEl={htmlElementRef} source={integration}> and

const target = args.scopeEl || document;
target .addEventListener("click", handleAnchorClick);

Or a bit more advanced (and potentially buggy): automatically find the nearest parent HTML element for <Router>.

Steps to Reproduce the Bug or Issue

1. Go to Home (/) if not already there and open console
2. Click on any of the "Post X (modal)" links
3. Clear console log
4. Click on any of the "Post X (modal)" links in modal (links under router 2)

You can see in logs [router 1] set global loc: that even though this link is rendered under second <Router>, it will still invoke the setter for first <Router> integration.

Expected behavior

Link behaviour respects the context.
Link rendered under <Router1 source={integration1}> should invoke the integration1 setter.
Link rendered under <Router2 source={integration2}> should invoke the integration2 setter.
