How to get the initiator element on a turbo stream response

[Mado13]

I'm using Turbo Stream responses in a Rails 7.2 app. On the frontend, I'm listening for events like turbo:submit-end and other Turbo Stream events. These events are fired on the global document, which is where they have to be listened to, but none of them include a reference to the initiator—the link_to helper I used with data-turbo-stream="true" to trigger the flow.

Turbo is creating a synthetic form and submitting it, and in the response, it considers that form to be the target.

In a real-world example, the page might have multiple forms and links doing different things. I can't just listen globally for turbo:stream-end and say “if success, do X” (in my case, I just want to toggle a class). Whether or not I use Stimulus doesn’t matter here (I’m still using jQuery, though I’m phasing it out). The issue is that there's no reliable way to identify which element triggered the stream, and that really limits what you can do with it.

Am I missing something?
