[csswg-drafts] Pull Request: [css-break-3] Add the concept of grouping boxes

Psychpsyo has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== [css-break-3] Add the concept of grouping boxes ==
This improves layout in tables and grid containers which contain cells that span across multiple rows which may be broken into separate fragmentainers.

Here is an example of what behavior this aims to improve:
<img width="1310" height="653" alt="489477628-789bbcb1-69ab-4781-872d-0378335b3d6f" src="https://github.com/user-attachments/assets/2e68a4da-cdef-4335-8a5f-dc3f41d91875" />

This is not meant to be a requirement for UAs, but rather just a suggestion. I hope the use of "should" instead of "must" has that power. (if not, that can be changed)
