& in titles are stripped out in full banner

[jstsch]

When the website name contains a & (ampersand), it gets stripped out of the main banner. Whether it's included as an entity or the & character itself.

Example:

var DIGITAL_CLIMATE_STRIKE_OPTIONS = {
      websiteName: 'First & Last'
  };

Observe that the text becomes: 'The First website is joining the Global...'

I've worked around it by including the ＆(unicode U+FF06 character) for now :) (but it looks not so great of course)
