Subject: [PATCH] add an initial state for 'browser_setting' variable.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After the file browsersettings.json is uploaded, it’s necessary
to create an initial state for the user’s browser preference settings.
This enables the Collabora iframe to include the POST variable and
serve preprocessed HTML with accessibility features enabled, for example.
