I've noticed this as well, so have ensured that my dataprovider doesn't have an empty string in it. Not sure what the actual bug is, but I experience it with the Adobe AutoComplete component (which extends ComboBox).

When menu is dropped down there are several empty items in it, which do not exist in data provider. There is a rule - every 5th item in it is empty. Is that a bug? -- A vivid and creative mind characterizes you.
