Linting doesn't work during typing the text

[dmitsermar]

Environment data

VS Code version: 1.18.1
Python Extension version: 0.8.0
Python Version: 3.6
OS and version: Win7SP1, x64

Actual behavior

Linting does not work during typing the text even if parameter python.linting.lintOnTextChange = true.
Linting on file save works as expected.

Expected behavior

Linting highlights syntactical and stylistic errors in my source code as I type it

Steps to reproduce:

• set to "true" the python.linting.lintOnTextChange;
• create a Python file and type some code with errors - linter doesn't highligt the errors;
• save the file - linter highlights the errors

Logs

Output from Python output panel
empty
Output from Console window (Help->Developer Tools menu)
empty
