Thanks for the report! This is now fixed in v1.4.4.

µJS now resolves URLs using the native URL constructor and compares origin against window.location.origin. This means all same-origin URLs are correctly recognized as internal: - Absolute URLs: https://domain:port/page - Relative URLs: ../page.html, page.html - Local paths: /page (already worked)

Hash-only links (#section) are intentionally left to the browser for native anchor scrolling.
