Pattern: Writing to document.domain
Issue: -
Do not write to document.domain. Scripts setting document.domain to
any value should be validated to ensure that the value is on a list of
allowed sites. Also, if your site deals with PII in any way then
document.domain must not be set to a top-level domain (for example,
live.com) but only to an appropriate subdomain (for example,
billing.live.com). If you are absolutely sure that you want to set
document.domain then add a tslint suppression comment for the line.
