OS and Theia version:

Diagnostics:

[akosyakov]

We should upgrade to latest typescript built-in and also to latest typescript for Theia repo

If it does not help, we should reproduce it in VS Code and report for typescript and VS Code.

[akosyakov]

I cannot reproduce it. We switched to latest typescript and built-in vscode extension.
