Line comments right after preprocessor directives break highlighting.

[teo-tsirpanis]

Consider the following snippet:

public class Foo
{
    void Bar()
    {
#pragma warning disable CS0000 // Internal compiler error
        var x = Baz(1, 2, 3, out object error);
#pragma warning restore CS0000 // Internal compiler error
    }
}

We have a preprocessor directive, a line comment on the same line, and some code right on the next line (not very unusual in real-world code). The line after the directive gets weirdly highlighted:

This does not happen we remove the line comment, or add a blank line or block comment after the directive. It also happens if we add some more line comments in the lines between the directive and the code.

From what I saw, the whole line belongs to textmate scopes meta.preprocessor.cs, source.cs. Maybe that happens because the line comment consumes the end of line, and the directive cannot match (?<=$)?
