Please update the appropriate steps in above post.

1. Which extensions are installed in code and code is reloaded after installating those extensions and they are activated.
2. What is your gist ID, and which installed extensions are missing in your gist.

As I already mention in the issue, the VSCode BuildIn plugins.

Those are default installed in every VSCode installation.

The issue as its already explaining, if one disables some of them, they sync-plugin does NOT take that into account. e.g:

1. Install VSCode + Sync plugin
2. disable CSS build in language support
3. upload config within gist with sync plugin
4. download this, with sync plugin, on another machine
5. the build-in language, CSS, which one disabled on the first machine, is not disabled on this second machine (after config synced with the plugin)
