In `flex-direction: column` layouts, a flex item's intrinsic height may depend on its width, but the width is calculated *after* the intrinsic height is required. Unfortunately, the specification doesn't tell us exactly what to do here (missing inputs to intrinsic sizing is a common problem) so we take the solution that flexbox applies in 9.2.3.C and apply it to all intrinsic height calculations within FlexFormattingContext: if the used width of an item is not yet known when its intrinsic height is requested, we substitute the fit-content width instead. Note that while this is technically ad-hoc, it's basically extrapolating the spec's suggestion in one specific case and using it in all cases.
