A simple reproduction of the issue can be seen here:
https://jsfiddle.net/8uxf8187/1/

The panel is shown using the JQuery animate method, when it shows the floated elements are hidden. If the area is redrawn then they are shown again (e.g. scrolling/resizing etc.).

This can be worked around by causing the elements to be redrawn after the animation has been finished, this has to change the CSS enough to cause the redraw (in this case I've changed the position to relative which triggers the reload without changing the effect):
