Common issue fixes

* in playground sample, when change sliderType from "min-range" to "default" the handle doesn't move to actual value - resolved
* when lineCap is "round" or "square", while click on the linecap the value not changed - resolved
* when lineCap was set as "square", previously we don't have the outer border support. Now resolved that.
* previously the slider instance was saving in the ID as global variable, now removed that due to memory issue
