<p>OSM uses the R2 gem to "flip" CSS for right-to-left languages.  In <a href="https://github.com/openstreetmap/openstreetmap-website/pull/1585" class="issue-link js-issue-link" data-url="https://github.com/openstreetmap/openstreetmap-website/issues/1585" data-id="242877918" data-error-text="Failed to load issue title" data-permission-text="Issue title is private">#1585</a> I explained how this is causing all but one icon to go missing on these languages' pages on OpenStreetMap.</p>
<p><a href="https://user-images.githubusercontent.com/643918/28294715-985565f2-6af7-11e7-80bd-6f79cdb6825a.png" target="_blank"><img src="https://user-images.githubusercontent.com/643918/28294715-985565f2-6af7-11e7-80bd-6f79cdb6825a.png" alt="image" style="max-width:100%;"></a></p>
<p>The issue got back to the R2 gem developer and he released a new version of the gem (0.2.7) where you can place a <code>/* no-r2 */</code> comment inside a CSS block and have sprites and other items not be modified. Due to how we use SASS, I believe that the comment needs to be inside each block.</p>
