+/**
+ ResizeTestHelper is a framework to test ResizeObserver
+ notifications. Use it to make assertions about ResizeObserverEntries.
+ This framework is needed because ResizeObservations are
+ delivered asynchronously inside the event loop.
+
+ Features:
+ - can queue multiple notification steps in a test
+ - handles timeouts
+ - returns Promise that is fulfilled when test completes.
+ Use to chain tests (since parallel async ResizeObserver tests
+ would conflict if reusing same DOM elements).
+
+ Usage:
+
+ create ResizeTestHelper for every test.
+ Make assertions inside notify, timeout callbacks.
+ Start tests with helper.start()
+ Chain tests with Promises.
+ Counts animation frames, see startCountingRaf
