I wrote an example, but JSFiddle does not support IE8, please create a new native test.

This example is the test SlideDown and SlideUp.

Run error message: SCRIPT5009: “cloned”未定义 velocity.1.4.2.js (546,6)

After I am in the No. 546 line "return cloned;" instead "return clone;" , There is no error message during the run, but not working.

After debugging: Breakpoint 2815 line

if ($.isPlainObject(propertiesMap) && !Type.isEmptyObject(propertiesMap)) { propertiesMap value seems to have a problem.
