'' in Stimulus controller not working with Rails 6.1 defaults

Hoping someone can help me this. I have a Stimulus (2.0) controller that updates the database on a focusout event (see simplified version below). I’ve been having problems with this since upgrading to Rails 6.1. If I use config.load_defaults 6.0 in my application.rb file, it performs as expected, but when I switch to config.load_defaults 6.1 it no longer works (though I don’t have any issue with database updates via the Rails controllers). The event listener is still triggering as expected, but it doesn’t seem like is doing anything.

This may be strictly a Rails issue but I was hoping someone here might have an idea what’s causing it. I’m not really sure how to go about debugging this.

import { Controller } from "stimulus"
import Rails from "@rails/ujs";

export default class extends Controller {
    static targets = ["title", "chapterForm"]

    connect() {
        let title = this.titleTarget;
        let chapterForm = this.chapterFormTarget;

        title.addEventListener('focusout', () => {
  , 'submit')


Never mind, I figured it out. Has nothing to do with Stimulus; it’s related to this not-so-well-publicized change in Rails config defaults:

I have the same problem.

Wouldn’t we expect to submit the form as a HTML request with remote forms disabled?

I don’t understand why would seem to take no action.
