The new voting ability for tags is finally in! yay!
but.
In beta, possibly coinciding with the introduction of tag voting, autocomplete no longer suggests anything for the 'tag' input field.

Expected behaviour:
autocomplete would work in this field, as it has in the past. It's useful for remembering previously used tags, avoiding typos etc.

New behaviour:
autocomplete no longer suggests anything in the 'tags' input field.

Possible reason:
The input field used to have a name attribute, but no longer does. Some (all?) browsers use the name attribute when suggesting autocomplete.

In production: <input class="tag-input" name="tag.tags" value="" type="text">
In beta: <input class="tag-input" style="flex-grow:2;" data-reactid=".0.2.0" type="text">

if possible I'd really really like to have this capability back.
