<datalist> searches using "contains" instead of "starts with"
Firefox (since ages) and Chrome (since 08/2016) search datalist items using "contains". However, IE still uses "starts with" to filter datalist items.
It can easely be tested here:
I think IE should adopt a "contains" approach too to filter items, as it is by far more useful/practical ...and would behave similarly to FF/chrome.
