-webkit-box-ordinal-groupproperty defaults to1for unstyled items. The standardorderproperty defaults to0. Passing the same$valto both means the relative ordering may differ in old WebKit when$valis0or negative. Current call sites use2and3, which work correctly because unstyled siblings default to group1/ order0and still sort first.

Flexbox on .small-action looks good, but float on child elements is now a no-op.
With .small-action as a flex container, float: left on .topic-avatar (line 270) and float: right on button (line 309) are both ignored per the CSS spec. The avatar still appears on the left naturally (flex items flow left-to-right), but the button will no longer be right-aligned since float: right has no effect inside a flex container.
To restore the right-alignment, add margin-left: auto to the button rule (or to .small-action-desc if you want the button pushed to the far right).
Proposed fix
button {
background: transparent;
border: 0;
- float: right;
+ margin-left: auto;

-ms-align-items on line 121 is not a valid CSS property.
The IE10 flexbox property is -ms-flex-align, which is already declared on line 120. Line 121 (-ms-align-items) is a no-op in every browser and should be removed.
Also, note that -webkit-box-align and -ms-flex-align use a different value vocabulary than standard align-items (e.g., start/end vs flex-start/flex-end). The current call sites pass center and baseline, which happen to be shared values, but passing flex-start or flex-end would silently fail in legacy browsers.
Proposed fix
`@mixin` align-items($alignment) {
-webkit-box-align: $alignment;
-webkit-align-items: $alignment;
- -ms-flex-align: $alignment;
- -ms-align-items: $alignment;
+ -ms-flex-align: $alignment;
align-items:$alignment;
