-      // (a) we happen to ship a new Bootstrap release soon after the release of a new ESR,
-      //     such that folks haven't yet had a reasonable amount of time to upgrade; and
-      // (b) the new ESR has unprefixed CSS properties/values whose absence would severely break webpages
-      //     (e.g. `box-sizing`, as opposed to `background: linear-gradient(...)`).
-      //     Since they've been unprefixed, Autoprefixer will stop prefixing them,
-      //     thus causing them to not work in the previous ESR (where the prefixes were required).
