I am listing couple of problems here concerning dropdown panel of comboboxes. please refer jsfiddle example given below and attached screenshot.
1. the dropdown panel doesn't hide when focus (mouse click) is set directly on another combobox. If mouse is clicked elsewhere on the page, the panel is hidden as expected.
2. In Internet Explorer (Version 11), when two comboboxes are clicked one after the other, and a alert is shown for the selection made on the first combobox, the dropdown panels of both the comboboxes are shown.
3. The alert box is shown behind the dropdown panel. As a result, the alert message gets partially hidden and the dropdown panel is active (the alert's modal has no effect on it).
