Intellisense not working consistently on 1.41

[tomonline]

Issue Type: Bug

Hi,

I am using VS Code 1.41 on Windows and I noticed that there was an issue with Intellisense suggesting auto-imports.

If an import was missing, the item is red-underlined, and pressing Ctrl+Space works once by showing suggested imports. However, if I try to use it a second time, on the same file, same import or even anywhere in the application it fails to work, returning just 'No suggestions'

Interestingly though, hovering over the item with the red underline and then selecting 'Quick Fix' does provide the suggested import consistently. However, this is a lot slower than the keyboard method.

I have downgraded back to 1.40.2 and the functionality has returned with Ctrl+Space working consistently again.

Could you suggest what is the issue here with 1.41?

Thanks
Tom

@tomonline I'm guessing you are talking about JavaScript? Can you please provide short example that exhibits the problem? Thank you!

Same issue on Darwin x64 19.0.0 (Catalina).
VSC Version: 1.41.1

example: const request = require('request'); // request. - No intellisense to give properties

@kieferrm Apologies - yes it's javascript, though to be specific, it's a Typescript file generated from Angular CLI.

VS Code version: Code 1.41.1 (26076a4, 2019-12-18T14:58:56.166Z)

The first time I invoke intellisense via Ctrl+Space, VSC suggests which file to import:

The scond time I invoke intellisense via Ctrl+Space, VSC provides no suggestions:
