@bcoe @cspotcode Any thoughts? Thanks in advance.

Hello, is anyone paying attention to this small fix? I am expecting this to be merged and backported to 18.x as soon as possible. Thank you guys.

Pinging some members with source-map-cache review experience. Hope this doesn't bothers much.

This looks like a trivial fix but I think it would be better to raise the issue to https://github.com/tc39/source-map-rfc as well.

CI: https://ci.nodejs.org/job/node-test-pull-request/56059/

The failure doesn't seem related to this PR. sequential.test-watch-mode-inspect was marked flaky.

CI: https://ci.nodejs.org/job/node-test-pull-request/56095/

Thank you for your contribution!

lib: don't parse windows drive letters as schemes
We were incorrectly parsing windows drive letters as schemes. This was

polluting the source map cache with malformed file paths.
