I'm an avid user of typescript-ts-mode, and I'm also very interested in seeing expanded use of font-lock-variable-use-face in Emacs. IMO it really helps highlight key structural elements of the code.

Unfortunately typescript-ts-mode (and tsx-ts-mode) is not very good, nor consistent in highlighting variable use using these new faces.

Attached is a patch which seeks to remedy the situation. Let me know what you think :)
