native es-Module IntelliSense import does not import correct path.

Steps to Reproduce:

1. Create an ES Module and export something
   export const something = 'something';
2. Create another file and start typing 'something' to trigger suggestions
   
3. Press 'Enter' or something to apply this prompt
   
4. Run in Browser (or Node.js with --experimental-modules flag)
   

Does this issue occur when all extensions are disabled?: Yes

My goal is to import files using the IntelliSense prompts for the correct module (native JS with ES Modules).

I would expect the path to be correctly injected, however the extension is missing, which does not comply with ES module standards for paths.

What I am seeing instead, is an almost complete path. But it is missing the file extension (if it is needed)

Currently, I am supplying the file extension manually afterwards the IntelliSense inserts the path.

This is only a problem when using ES Modules and browser/Node.js, as the cjs pattern is fine with resolving the extension (either at compile or run time, respectively)

Thanks for the detailed report. This is currently tracked upstream by microsoft/TypeScript#28288

I've marked it as a priority feature for TS since we see this reported fairly often
