On selecting a different item of the balloon-selector field, it should trigger the changed value to any fields that depends on it via the trigger API.
On selecting a different value nothing happens. Only when the form is saved and the page reloaded, the dependent field鈥檚 visibility changes.

Thanks for this report, that GIF is helpful for reproducing this. I can't review it right now as I'm away until March 7th, but perhaps @daftspunk can take a look. Feel free to dig into the code yourself and submit a PR to fix it if you can. If it's super urgent, post a bug bounty and ping the IRC channel and Slack team.
