The way we used `ElementType` caused a significant increase of resource usage for TypeScript. I can’t really explain it, but this fixes it. I’m personally inclined to say people should avoid using the `JSX` namespace, but I see no other way around it. Without this change, autocompletion in my editor takes a noticable time to load. Now it’s instant. On my machine this halves the time of running `tsc -b` from ~15s to ~7s. Closes #883

There was a problem hiding this comment.
I'm neutral on this.
I'm cautious about applying a fix we don't understand to a problem we don't understand.
That said nothing about this code seems particularly worrying.
