• VSCode Version: 1.48.2 (user setup)
• OS Version: Windows_NT x64 10.0.18363

Steps to Reproduce:

1. Write a JavaScript class with a private method
2. Attempt to auto-complete the private method somewhere.

Expected outcome:

• Private method is autocompleted correctly

Actual outcome

• Private method is autocompleted with some extra characters

See the following screenshots

Does this issue occur when all extensions are disabled?: N/A autocomplete doesn't recognise JavaScript at all if extensions are disabled. I did try this with a vanilla install of Insiders (no extra extensions enabled) and the problem still occurs
