What is the current behavior?

It was possible for esbuild to break out of the sandbox and find the .ts file inputs, this could be seen if the .ts file was generated, as it would live in bazel-out/

This also fixes an issue where external npm modules may not have gotten resolved correctly when bundling

Issue Number: N/A
