`AbortError: signal is aborted without reason` is bubbling up when using loader with basepath

[rhuanbarreto]

Which project does this relate to?

Router

Describe the bug

Initial conditions:

• Router configured with basepath: "/somepath"
• Loader in the root route that uses the abortController

Action:

• Access the frontend at "/"

Outcome:

The loader gets aborted during the first render cycle (correctly) due to a redirect to the basepath. But the AbortSignal is sent without a reason, which defaults to a DOMException AbortError: signal is aborted without reason that gets caught by the ErrorBoundary and it doesn't let the application render.
