Break points between items of a column-direction flex line

The second card below declares break-before: page. A column-direction line's items are stacked in the block axis, so this is a real break point between two items of the same line - it now moves that item (and anything after it in the line) onto the next page instead of being read only from the container's very first child.

Item 1 — stays on this page

Item 1 entry 1. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Item 2 — break-before: page

Item 2 entry 1. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Item 3 — follows item 2

Item 3 entry 1. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
