ENYO-3138: Recalculate scroll thumb metrics on resize
ENYO-3138: Recalculate scroll thumb metrics on resize

Issue:
NewThumb is created from scratch to support new smart share use case. Now we have new use case of resize the new data list at runtime. And, current version of scroll thumb doesn't include that logic.

Fix:
Recalculate metrics on resize handler. So that it can draw itself in correct size and position.

Add super call

Add check for getAbsoluteBounds to avoid unnecessary calculation.
