Bonzai Intranet masterpage
Bonzai Intranet uses a custom masterpage that contains a number of additional attributes used to load javascript libraries.
As per Microsoft best practices the Bonzai Intranet masterpage does not remove any SharePoint components and as part of the Bonzai Intranet service we ensure that any changes that Microsoft makes are tested before being released to clients.
For more information about customer masterpages, see Master pages in the SharePoint Add-in model
