  <!-- In all of the subtests here, each flex item's automatic minimum width is
       resolved directly from its content size suggestion. Notably, these items
       *do not* get a "transferred size suggestion", because they are all
       *non-replaced* elements; and "transferred size suggestion" is only used
       for resolving automatic minimum sizes on *replaced* elements. However,
       note that we do "transfer" sizes through the aspect ratio, as part of
       computing the content size suggestion and/or flex base size. -->
