1786399 - Fix named page fragmentation on flexbox and other non-block-level frames

Status: RESOLVED FIXED

(Core :: Layout, defect, P2)

Description

[Emily McDonough [:alaskanemily]]

As per the CSS page3 spec, the page property only applies to frames that can create class-A breakpoints. From the fragmentation spec, this is only block-level frames and layout orthogonal table components, and does not include flex items.

This does fix issues with flex-box items, but does not yet handle table layout.
