Syntax highlighting breaks when opening bracket of a method is placed in a new line

The following code placed in a class breaks syntax highlighting:

public void Routine
(
  IInterface Interface0,
  IInterface Interface1,
  IInterface Interface2
)
{
  string One = "";
  string Two = "";
  string Three = "";
}

interface IInterface
{
}

Beginning with the second instance of IInterface and after the method body, everything is white -- in more complex projects, somewhere it works again later in the file.

Removing the newline after public void Routine does not cause the issue:

I am aware that this appears to be a "strange" coding style; it makes reading constructors with loads of dependency injections much cleaner though (issue happens with both methods and constructors).

There's not much we can do about the first example as colorization is handled by running regular expressions in a line-by-line fashion. When the open and close parens are both placed on separate lines, it's pretty much impossible to detect.

I'm marking this as a bug for now. However, there may not be much we can do about the issue. VS Code colorization is handled by scanning a document line-by-line using regular expressions. This provides colorization that is generally "good enough", but won't every be perfect. If there's not enough information on a single line to identify a particular construct, it's unlikely that it will be colorized precisely.

Note that this is related to #61.
