Inaccurate stacktraces and can't debug from source files when using TS or other transpiled languages

[ScottPierce]

Description

I am not able to get proper stacktraces from dev or properly debug the from my source files because sourcemaps for .js files seem to be ignored in dev.

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Run the provided project
2. See the following crash:
   

Expected Results

The stack trace and debugging aren't taking advantage of the provided source-maps for the files in ./lib at all. I should get a stack trace that references the .kt source files, and I should also be able to debug/breakpoint from the .kt source files when I attach them in chrome.
