C_Cpp.vcFormat.space.withinSquareBrackets bug on first line

Bug Summary and Steps to Reproduce

Bug Summary:

C_Cpp.vcFormat.space.withinSquareBrackets setting doesn't insert a space within the square brackets for the first designated initializer for an array.

Steps to reproduce:

1. Set "C_Cpp.vcFormat.space.withinSquareBrackets": true, in settings.json.
2. Create a new C file
3. Put in this code:

int array[] = {
    [0] = 0,
    [1] = 1,
    [2] = 2,
};

4. Format with C/C++.

Code should be formatted to

int array[] = {
    [ 0 ] = 0,
    [ 1 ] = 1,
    [ 2 ] = 2,
};

Instead, the file is formatted to

int array[] = {
    [0] = 0,
    [ 1 ] = 1,
    [ 2 ] = 2,
};

Additional context

No response

Reproduce the issue in VS Code with C_Cpp.vcFormat.space.withinSquareBrackets enabled and the designated-initializer example from the report. Trace the C/C++ formatting path used by the extension; done means the first array initializer receives spaces inside its brackets, matching the later initializers.
