Using the defintionsFromContext webpack helper does not mark controllers as registered

[SleeplessByte]

We are using Debian Rails which is at 6.1 for the time being. Note that this Rails version isn't deprecated and will continue to receive security fixes even after Rails stops supporting it, unless there is a new stable Debian.

Using definitionsFromContext from the @hotwired/stimulus-webpack-helpers package does not mark Stimulus controllers as registered.

import { definitionsFromContext } from '@hotwired/stimulus-webpack-helpers';

const application = Application.start(document.documentElement);

// Normally you'd need to add the webpack env types, but since we'll migrate
// away (in Rails 7), and we know the signatures here, it's ignored and casted
// as any instead.

// @ts-ignore
// eslint-disable-next-line no-undef
const context = require.context('../controllers', true, /_controller\.ts$/);
application.load(definitionsFromContext(context));

declare const window: Window & { Stimulus: Application };
window.Stimulus = application;

The result in the Stimulus Controllers view:

I don't know if this is related, but I don't see any autocompletion in .html.erb files. I would expect them to not show for unregistered controllers, hence me opening this issue.

Trying to circumvent it by using the Register controller definition on the stimulus application yields the following error message:
