The getComputedStyle method cannot get the real computed value of the width or 
height property, so the shrink_to_fit_percentage_child detector used a tricky 
way to get the real computed value of the said properties.
Setting an element's 'display' property to 'none' and restoring it will cause 
the correlative elements to repaint very slowly, this is the root cause.
The solution is to use cloneNode instead of the original way.
