Multi-line function arguments can not be syntax highlighted

[aziz]

TS and JS Grammar Extension version: 0.0.26 / latest

Code

// Please include a code snippet that demonstrates the issue
const documentFilter = (
  searchText: string,
  documents: IKeystoneDocument[]
): IKeystoneDocument[] => {
}

function arguments in the example above cannot be highlighted. putting only one of them in the first line fixes the issue, something like this works:

const documentFilter = (searchText: string,
  documents: IKeystoneDocument[]
): IKeystoneDocument[] => {
}

We can not do it since the formatting is done using prettier automatically.

This is duplicate of #481 and limitation to the tmLanguage grammar syntax which cannot look ahead over multiple lines and cant lookback in multiple lines

Released VS Code Extension version 0.0.33 that contains #552 which should address issues reported here. After letting it bake in that extension for 2-3 weeks, I could merge #552
