Navigating away from config UI results in changes to active field being lost

[Colengms]

The repro is to modify the includePath field (or likely any field) in the Configuration UI (not directly in the JSON file). If you navigate to another document after making an edit, without otherwise deactivating the text field, the edit will be lost.

It's possible this may be an issue with VS Code itself not delivering a deactivation event that it should be.
