42 <!-- In this testcase, the first flex line initially has a cross-size of |
|
43 10px, and the second flex line has a cross-size of 30px. Both lines are |
|
44 stretched by 10px each (to hit the container's total cross-size, 60px). |
|
45 Then, we handle "visibility:collapse" and convert the collapsed item |
|
46 into a strut with the second line's stretched cross-size (40px), and we |
|
47 restart flex layout. This strut then ends up in the *first* line (since |
|
48 it has 0 main-size), which means both flex lines end up being 40px tall. |
