Fix: Radio checked state lost when _resizeAuto run

[michaelcm]

• Name attributes must be removed from elements before the sizing clone is injected into the page to avoid adverse affects with selected radio inputs

When a checked radio is inserted into the dom with the same name as another radio that is checked, the original radio is unselected... effectively loosing the selection.

This patch removes name attributes before the cloned table is inserted into the dom for sizing..
