debug code run inside vm doesn't support inline sourcemaps

[denghongcai]

• Version: v14.5.0
• Platform: Darwin Kernel Version 19.5.0
• Subsystem: vm
• Chrome Version: 86.0.4207.0

What steps will reproduce the bug?

testcase: https://github.com/denghongcai/node-vm-sourcemap-test-case

I insert a debugger statement in src/index.ts 's sayHello method

not working step (use vm):

npm run build
npm run inspect

in devtools, no sourcemap detected

working step (no vm):

npm run build
npm test
npm run inspect-index

seems if vm run code with inline sourcemap, it will not be parsed by chrome devtools?

How often does it reproduce? Is there a required condition?

always

What is the expected behavior?

I expected when debug in devtools, sourcemap will be parsed, displayed correctly

can you report this to https://bugs.chromium.org/p/chromium? devtools bugs are in their scope.

@devsnek ok, https://bugs.chromium.org/p/chromium/issues/detail?id=1107705

still keep this issue open, don't know whether it is related to Node.js implementation about multi context debug
