Disable autocomplete google chrome in mailbox

The autocomplete function of google chrome in the recipient field in the form when you compose a message, usually covers the auto completion of the dolphin. With this change solved:

in ====> /plugins/jquery/jquery.ui.autocomplete.min.js

change:

attr("autocomplete","off")

by:

attr("autocomplete","nope")

google chrome ignores off

Hello!

Thank you for your solution, but may you please specify your Chrome and Dolphin versions? In my Chrome 71 and Dolphins 7.3.5 and 7.4.0 autocomplete works as should.
