markdownlint: MD047/single-trailing-newline bug?

Reproduction steps:

1. git clone git@github.com:v8/v8.dev.git && cd v8.dev
2. npm install (note: this includes markdownlint-cli@0.15.0)
3. npm install markdownlint-cli@0.16.0
4. markdownlint src/**/*.md fails with the following error message:

src/blog/scanner.md: 95: MD047/single-trailing-newline Files should end with a single newline character

But, the last character in the file is definitely a U+000A LF character, as evidenced by hexdump:
