JS Events that don't bubble (progress, loadedmetadata, etc)

Question

I found out that certain events on the video/audio tag don't bubble (loadedmetadata, progress, etc). Is this against the standard or is it common for other events?

How am I supposed to know what events are supposed to bubble or not bubble?

Answer 1

1. You can test it...
2. readonly attribute boolean bubbles; check this property of the event.

bubbles of type boolean, readonly

Used to indicate whether or not an event is a bubbling event. If the event can bubble the value is true, else the value is false.
