HTMLHint extension not working in VSCode 1.48 and above

Issue Type: Bug

If I install newer version of VS Code (above 1.47), HTMLHint extension stop showing errors of html documents. I was forced to downgrade VS Code in order to keep functionality of the extension.

VS Code version: Code 1.47.3 (91899dc, 2020-07-23T13:12:49.994Z)
OS version: Windows_NT x64 10.0.18362
