Changing `C_Cpp.enhancedColorization` does not get applied synchronously when doing a side-by-side view

[michelleangela]

Steps to reproduce:

1. Open settings.json and a source file side by side.
2. Change C_Cpp.enhancedColorization to Enable then to Disable. Side by side sync works.
3. Change C_Cpp.enhancedColorization to Enable after it was disabled. Side by side sync does not work. May have to edit/save the file or reopen file to apply changes.

Is this a text-mate or VS Code bug?

Doing a "Restart IntelliSense For Active File" fixes it or doing a Save and switching docs causes it to refresh the IntelliSense semantic colorization. Seems like a bug to me (with our handling of the settings change), but low priority.

Verified on C/C++ 1.23.4(pre-release), this issue has been fixed:
