Manual test steps:

Step 1: Click the "make busy" button to make main-thread busy for 2 seconds.
Step 2: do several clicks on "click while busy" while busy to generate long-latency inputs.
Step 3: observe in the "timeline" section that the long-latency clicks are captured by the observer.
Step 4: do step 1 to step 3 for the iframe. Observe that the observers only observe input events within its frame.
