This adds the
TabContainerChangeEvent
, rather than usingCustomEvent
which is not a best practice, and existed mostly becauseEvent
used to not be extensible.Using
TabContainerChangedEvent
we can put properties directly on the event, rather than the awkwarddetail
prop.In addition to this, I've added the
onTabContainerChange
andonTabContainerChanged
props to the element, which allow the "old school" assignment of the property to add an event listener. This allows frameworks like React to seamlessly use these events too. We did this in github/relative-time-element#246
