[css-grid] Revert r789122 for performance reasons

r789122 tried to solve bug 1103592, which actually was a flex problem
unrelated to grid, and was later fixed by r782793.

Therefore, r789122 wasn't actually needed, and caused a perf regression.
So this patchs reverts its layout changes. The WPT test is kept, and
still passes.
