Closed Issue: ComboBox inside a Panel using CSS attribute display or visibility [26874]

Precondition: ComboBoxes are inside a panel using CSS attribute display set to 'none' or visibility attribute set to 'hidden.'

Bug: when display value is set to 'inline' or 'block' the ComboBoxes are not rendered correctly. The down arrow is tiny and does not work. When the visibility property is set to 'hidden' the down arrow button remains visible, though it renders correctly when value='visible'.
