[Flow] Nested Generic Types break syntax highlighting

[vctrshn]

It seems like using nested generic types ends up breaking syntax highlighting for the rest of the file.

Minimal Repro

// @flow                                                                                                                                                                                                                                                                                                                                       
const OOF = new Map<number, Map<number, string>>();                                                                                                                                                                                                                                                                                            

export function thing(): Array<number> {                                                                                                                                                                                                                                                                                                       
  return [1, 2, 3];

Formatting the code this way doesn't cause the same problem, if it helps track down the root cause:

I commented out this line and it seems to be working on my machine now. Not sure what the ramifications are.
