Identifier highlights do not appear with keyboard movement

[sandersn]

Identifier highlights do not appear when you move the caret with the keyboard, but do when you move it with the mouse. I tested this on TS and JSON files.

To Reproduce

Open a TS file:

var abcde = 1
console.log(/*1*/abcde)

Use the keyboard to move to the point marked /*1*/. It does not matter if you are in insert mode or normal mode, whether you use arrow keys, hjkl or something like fa.

Expected behavior
Both instances of abcde should be highlighted. Neither are.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.8.1
• VSCode version:1.36.0
• OS:Linux x64 4.15.0-51.generic (it is some version of Ubuntu)

Additional context
Works fine when clicking.
Works fine when Vim is disabled.

Oop, duplicate of #3044. That issue's title is really wordy.
