The carousal widget doesn't function quite right on the latest versions of steal and canjs. ``` "can": "^2.3.24", "steal": "^0.16.16" ``` There aren't any errors in the browser console, only warnings: `WARN: can/view/stache/mustache_core.js: Unable to find key or helper "slideNumber".` The first slide appears correct, but after switching to a new slide, there are multiple slides getting displayed.
