Issue Description

The .env file looks like this:

ENV_VAR=right # comment after
# ENV_VAR=wrong

Using npx tsx --env-file .env test.ts, the commented-out wrong variable is set during execution rather than the correct one. The conditions for this are:

• the correct one has a comment after the line where it's defined
• the wrong one appears below the right one

Run this MWE

npm install
npm run start
# or
npx tsx --env-file .env test.ts

This is a MWE for this GitHub issue on the tsx repo. When that is resolved I'll archive this repo.
