Configure date autocomplete in text fields

[Sam Speight]

A user pointed out that an autocomplete now pops up when typing a date, however the format is incorrect. 
Can I configure this somewhere? I either need to be able to match the format our instance uses, or turn it off entirely as it is detrimental in its current state.

Thanks
