Hi Nathan, this is basically due to the performance issue you filed before. I think, with current Nightly, you'll notice that we're using the old-style highlights in your example document, which is able to render much faster.
To make the modal highlighting mode work faster, we need some platform gfx optimization/ perf tracing work to get it there. But that seems a long way from today.
Regardless, I do think that reverting to the old mode resolves this issue.
