Subject: [PATCH] =?UTF-8?q?=E2=9C=85(frontend)=20cover=20the=20homepage=20?=
 =?UTF-8?q?messages=20widget=20button?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The homepage shows the messages widget button when the widget is
configured. A test ensures the loader init command is queued and the
loader script is injected, so a config regression cannot silently
remove the button.
