Base Tag Not Present
--------------------

PLIP #13705 removed the <base> tag from rendered templates, here we'll check
that in fact is not being injected in some other way.

  >>> from plone.testing.zope import Browser
  >>> from plone.app.testing import SITE_OWNER_NAME
  >>> from plone.app.testing import SITE_OWNER_PASSWORD
  >>> app = layer['app']
  >>> browser = Browser(app)

  >>> browser.open('http://nohost/plone/login_form')
  >>> browser.getControl('Login Name').value = SITE_OWNER_NAME
  >>> browser.getControl('Password').value = SITE_OWNER_PASSWORD
  >>> browser.getControl('Log in').click()

Create object

  >>> browser.getLink('Page').click()
  >>> browser.getControl('Title').value = 'Front Page'
  >>> browser.getControl('Save').click()

Check object view

  >>> browser.open('http://nohost/plone/front-page')
  >>> '<base' in browser.contents
  False

Check edit view

  >>> browser.open('http://nohost/plone/front-page/edit')
  >>> '<base' in browser.contents
  False

Check folder_contents view

  >>> browser.open('http://nohost/plone/folder_contents')
  >>> '<base' in browser.contents
  False
