Steps to Reproduce:

Not sure if same issue or a different one.

Without the addon:

With the addon:

All my TypeScript highlighting is screwed up.

The largest and most important file in my project is not highlighted at all from the middle down.

Still noticing this as well, mainly when using newer TS syntax like foo?.bar optional chaining or ?? operators. After lines containing syntax like that, the highlighting is incorrect or completely absent for the rest of the file down.
