Research direction
Reproduce the highlighting with the TypeScript Nightly extension using the multiline arrow-function example, then compare it with the version without the line break. Trace the TypeScript TextMate grammar rules responsible for arrow-function parameters. Done means the parameter type and delimiters receive the same syntax highlighting in both forms.
