title: VSCode syntax highlighting not working when using ?? - nullish coalescing operator
body: <p>Good afternoon! I'm working on react.js with typescript. Recently moved to a new computer and noticed that the syntax highlighting does not work correctly. This happens if there is a double question mark in the code (?? - nullish coalescing operator)</p>
  <p>VSCode version 1.26.0,
  I can’t install another version of the program, since this is a work computer, not a personal one.
  Please tell me how can I solve this problem? Attached 2 screenshots:
