See stack trace below. We set the override container logical height to -1
for the initial layout of a flex item so that we compute the correct size
for min-height. However, that messes with our cache for definite heights
because we would always set it to indefinite in such a case.

Instead, just don't cache these values. That way we will later compute the right
thing for resolving flex-basis, etc.

(FlexNG can't come soon enough...)
