From ff0b2f7a6f99f752b0c8ee4c1d597cbd420775c7 Mon Sep 17 00:00:00 2001
From: Jeremy Felt <jeremyfelt@git.wordpress.org>
Date: Mon, 23 Feb 2015 02:28:41 +0000
Subject: [PATCH] Provide proper label associations and descriptions throughout
 the network admin

* Add labels previously missing for many inputs throughout the network admin screen.
* Add proper `aria-describedby` attributes to provide better descriptions.
* Wrap grouped inputs with `fieldset` elements.
* Remove now unneeded `title` attributes when appropriate.

Props cfoellmann, afercia, rianrietveld.

Fixes #38406.
