I'm concerned about the change of type for PerformanceEntryList:
interface PerformanceEntryList {
     getter PerformanceEntry item(unsigned long index);
     readonly attribute unsigned long length;
     PerformanceEntryList getEntriesByName(name);

It basically removes all of the Array methods on the type (since it is
currently a sequence), such as forEach or map.

As a developer, it will be very inconvenient to iterate through the list
without forEach.

And we're possibly breaking deployed applications by removing the Array
