They have added the autocomplete function, but if you use it to complete a template name, and use the keyboard arrows to chose the option and press enter, it will insert the full template name, including the namespace. For example:

You're typing: { {Quo Than you chose the option "Quote" with the keyboard. It will insert { {Template:Quote}}, instead of { {Quote}}
