In short, when I enable “number children”, there’s a problem with the display of the numbers when the numbers get larger. The html element containing the number seems to have something like an “absolute” position so that if the number is say in the hundreds or thousands, it overflows and overlaps with the content of the item. (See the screenshot I attached). It’s possible to work around this of course (use a different font / keep the list shorter). Still I thought since this is probably unintended behavior I’d report it. Thanks!
