ReSharper 8.2: TypeScript IntelliSense fails for generic types

ReSharper seems to not be able to resolve types that the native VS TypeScript plugin is fine at.

For instance:

<string[]>[].map(s => s.)

If you get Intellisense at the "s." you'll notice it's falling back to the "just show every identifier we can find" mode instead of realizing that s is a string.
