[css-sizing] Is the last remembered size recorded if there is size containment in a single axis?

From https://drafts.csswg.org/css-sizing-4/#last-remembered

At the time that ResizeObserver events are determined and delivered, if an element has contain-intrinsic-size: auto, is capable of being a ResizeObserver target, but does not have size containment, record the current inner dimensions of its principal box as its last remembered size.

What if the element has contain: inline-size?

• The dimensions are recorded as the last remembered size, as would happen with no containment.
• The dimensions are not recorded as the last remembered size, as would happen with full size containment.
• Only the block dimension is recorded as the last remembered block size. This would imply that the dimensions are recorded independently, and probably it should be the same when contain-intrinsic-size has auto in a single axis (#7516).

Read the CSS Sizing Level 4 “last remembered size” and contain-intrinsic-size sections, then compare the inline-size containment behavior with the related issue #7516 and the cited CSS Containment and ResizeObserver definitions. Done means the Working Group has resolved which dimensions are recorded and the specification wording reflects that decision.
