Callback events? about tabby

[cferdinandi]

I tried adding an eventListener to 'tabby', but that is called before the tab is actually selected

The event is emitted after Tabby adds/removes all of the classes, but... it is also likely picked up by your event listener before the next repaint happens, which is why it can appear to fire before. See here: https://github.com/cferdinandi/tabby/blob/master/src/js/tabby/tabby.js#L179

For what you're trying to do, though, you'd be better served using some CSS

You can modify the [role="tabpanel"] and [hidden] attribute styles to suit your needs, or add a requestAnimationFrame() to your event listener to wait until after the next repaint if that helps.
