There's a heuristic that merges highlight boxes together when they are close by. It might need to be adjusted although it depends from books to books.

	let doNotMergeHorizontallyAlignedRects = true;
	let clientRects = getClientRectsNoOverlap(
	item.range,
	doNotMergeHorizontallyAlignedRects
	);

Could you share this book you used as an example?

Note that this is not high priority, so it probably won't be fixed (by the core maintainers) soon.

This is the one of books when i could reproduce this situtaion but like you said it probably depends from books to books because it is reproducable only on few books.
