  <title>CSS Test: Testing that strut formation (from visibility:collapse) happens *after* lines have been stretched</title>

  <!-- In this testcase, the first flex line initially has a cross-size of
       10px, and the second flex line has a cross-size of 30px. Both lines are
       stretched by 10px each (to hit the container's total cross-size, 60px).
       Then, we handle "visibility:collapse" and convert the collapsed item
       into a strut with the second line's stretched cross-size (40px), and we
       restart flex layout. This strut then ends up in the *first* line (since
       it has 0 main-size), which means both flex lines end up being 40px tall.
