Unable to disable hover for DateItem

Hi Isomorphic,

I am using the DateItem with setSelectorFormat(DateItemSelectorFormat.YEAR_MONTH)

On hover over the FormItem it shows "Choose a Year", "Choose a month", etc.

I need to disable this text on hover. I'm not able to find any property that does this. Can you please let me know if there is a way to disable the text on hover?

Thanks
Sharan
