Format braces on new line causes editor to scroll so that the top of the editor is at the opening brace

[lachy874125]

Type: Bug

1. Set user settings.json to:

{
    "editor.formatOnType": true,
    "C_Cpp.formatting": "vcFormat",
    "C_Cpp.vcFormat.newLine.beforeOpenBrace.function": "newLine"
}

2. Create a new file with a .cpp extension.
3. Type int main(){ and press enter.
4. The program puts the opening curly brace on a new line as expected but then it scrolls so that the topmost line is the one with the curly bracket. So I am not able to see int main(). I do not want it to auto-scroll to the opening brace. The same thing happens if I set the newLine setting for braces of blocks, namespaces, etc. I have tested this on two machines both with the same behaviour. My workspace settings.json is empty. Haven't been able to find anything online regarding this.

This does not appear to be a bug with our extension. Our extension does not send a message to VS Code to change the scroll view. VS Code is doing that after we send it the formatting results. You should file a bug with VS Code and tell them our extension sends VS Code the appropriate vscode.TextEdit[] and we're not doing any scroll change.

Also, the same behavior repros with "C_Cpp.formatting": "clangFormat" and Format Document with

int main(){
}

so it's unrelated to vcFormat or formatOnType.
