No intellisense to implement TypeScript interface when there is a negative number type union

Version: 1.32.1 (system setup)
Commit: 05f146c7a8f7f78e80261aa3b2a2e642586f9eb3
Date: 2019-03-08T00:51:49.278Z
Electron: 3.1.3
Chrome: 66.0.3359.181
Node.js: 10.2.0
V8: 6.6.346.32
OS: Windows_NT x64 10.0.17134

Steps to Reproduce:

1. Create a TypeScript interface with a property of negative number union type
2. Create a class to implement that interface
3. Alt enter the class name to see intellisense to auto fill required implmentations

Without negative number type union works

With negative number type union will not work

Does this issue occur when all extensions are disabled?: Yes/No
Yes

Tested on typescript@3.4.0-dev.20190315

Code:

interface X {
    value: -1 | 0 | 1;

}

class Y implements X {

}

I see the following debug failure:

[Trace  - 10:13:21 AM] Response received: getCodeFixes (18). Request took 2 ms. Success: false . Message: Error processing request. Debug Failure. False expression: Token end is child end
