[css-flexbox-1] flex-basis: max-content + aspect ratio should use aspect ratio same as flex-basis: content

[tabatkins]

Right now the flex base size rules have a special branch for an item with an intrinsic aspect ratio, a flex-basis of content, and a definite cross-size, to ensure that the item maintains its aspect ratio. These rules should also be invoked for other content-based sizes for the same reason.

The rule is a bit different from falling down into the generic layout case (step 3.E) because 3.E ends up invoking float sizing for such items, and the float sizing rules directly inspect the value of 'width'/'height', rather than using the more generic notion of "a definite width/height", and so they don't see that the cross size of the item has been fixed by Flexbox's special rules on when a size is definite.

Retracting; I think this was valid before we landed a lot of tweaks/fixes to how the *-content values treat elements with aspect-ratios, but now that that should work correctly, case E will handle them correctly.

(It might even be the case now that case B could be removed? I have to recall how max-content works precisely, and whether it's different from just "transfer the cross size". Anyway, not relevant to this issue.)
