Code like

var x = 1;
var y = 2;
var z = 3;
                                                v
var formatedString = $"Something {new { x, y, z }}";

triggers "SA1013 Closing brace should be followed by a space", but adding space after the } doesn't look right and also triggers "SA1013 Closing brace should not be preceded by a space" and the description for SA1013 states

A closing brace should always be followed by a single space, unless it is the last character on the line, or unless it is followed by a closing parenthesis, a comma, or a semicolon.
