Column Alignment

I have been using this patch in Production for 2 years now. No complaints or issues. I added some CSS to our theme to make blocks placed in the columns have equal height when selecting the "Stretch" option. Feel free to critique it.

// Make the columns truly "stretch" when placing blocks.
.align-items-stretch {
  &.layout-builder__layout {
    > div[class*=col] {
      display: flex;
      flex-direction: column;

      > div[class*="block-"] {
        display: flex;
        flex: 1 0 auto;
        flex-direction: column;

        > div.block__content {
          display: flex;
          flex: 1 0 auto;
          flex-direction: column;

          > div {
            flex: 1 0 auto;
          }
        }
      }
    }
  }
}
