Validate Secure Document Public API (secure-document)

This rule validates that only supported functions and properties of the document global are accessed.
When LockerService is enabled, the framework prevents the use of unsupported API objects or calls. That means your Lightning components code is allowed to use:
  • Features built into JavaScript (“intrinsic” features)
  • Published, supported features built into the Lightning Component framework
  • Published, supported features built into LockerService SecureObject objects

Prior to LockerService, when you accessed the document global, you could call any function and access any property available. When LockerService is enabled, the document global is “wrapped” by a new SecureDocument object, which controls access to document and its functions and properties. SecureDocument restricts you to using only “safe” features of the document global.
