Salsa formatting honours tab vs spaces setting only sometimes?

[alexdima]

Testing #2218

I have the following settings:

// Place your settings in this file to overwrite default and user settings.
{
    "typescript.tsdk": "C:\\Alex\\salsa\\node_modules\\typescript\\lib",
    "editor.tabSize": 4,
    "editor.insertSpaces": false
}

If I have a function indented with 5 spaces, and choose format, the 5 spaces get replaced with a tab:

function howdyAgain(name) {
     return 'hi';
}

If I have the same function indented with 4 spaces, and choose format, the 4 spaces do not get replaced with a tab:

function howdyAgain(name) {
    return 'hi';
}
