1791760 - Make containment logic Frame-aware

Status: RESOLVED FIXED

(Core :: Layout, task)

Description

[Martin Robinson (email:[e-mail])]

This bug tracks moving logic dealing with determining if an element has CSS containment to nsIFrame. Containment depends on both whether or not an element is skipping its content (for content-visibility: auto elements) and whether an element is a non-atomic, inline-level box. Both of these pieces of information are available with the frame.

Attachment: Bug 1791760 - Move GetContainSizeAxes to nsIFrame r=emilio

This will allow this function to eventually return an appropriate value
depending on whether or not content is skipped via content-visibility: auto. This change also starts looking directly at whether
content-visibility is skipping content or not, which should make it
compatible with a future content-visibility: auto implementation.
