Flex child won't fill width, breaking button alignment

Medium Severity

Adding flexbox() to .small-action makes .small-action-desc a flex item, but without flex: 1 or equivalent, it only takes its content width instead of filling the remaining space. Previously as a block element with padding-left: 4em, it naturally spanned the full container width. Now the float: right buttons inside .small-action-desc only float to the right edge of the narrower content-sized element, not to the far right of the .small-action container — a visible layout regression.

Order mixin has incorrect ordinal-group value mapping

Low Severity

The order mixin passes the same value to both order (default 0) and -webkit-box-ordinal-group / -moz-box-ordinal-group (default 1). The old flexbox properties need $val + 1 for correct mapping. With the current values used (2 and 3), relative ordering happens to be preserved, but the mixin is logically incorrect for general use.
