What OS are you using (uname -a, or Windows version)?

Darwin jdw-mbp.local 23.2.0 Darwin Kernel Version 23.2.0: Wed Nov 15 21:54:05 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T6031 arm64

What version Socket Runtime are you using?

0.5.4 (97fa3f7c)

What did you expect to see and what you saw instead?

new URL('./example.html', 'socket://com.my-app').origin returns the string 'null' but I would expect it to return 'socket://com-my-app'.
