+ * Bug 1801277 - Shim Microsoft virtual assistant.
+ *
+ * The microsoft virtual assistant will break when accessing the indexedDB that
+ * will throw a security error because the virtual assistant is under a
+ * third-party tracking domain 'liveperson.net'. The shim replaces the indexedDB
+ * with a fake interface that won't throw an error.
