ViewComponent / Turbo Double Render Bug

This repo is a minimal reproduction of a bug I'm seeing when using ViewComponent with Turbo.

Steps to reproduce

  1. Clone this repo
  2. Run bundle
  3. Run rails s
  4. Visit http://localhost:3000
  5. Click the "Create" button

Expected behavior

Turbo should submit the form, which results in a redirect and adds a flash message. Turbo should load the redirected page and replace the page content with the loaded page content (including the flash message).

Actual behavior

Turbo submits the form, which results in a redirect and adds a flash message. Turbo loads the redirected page twice, replacing the page content with the second page load. The flash message is lost in the process.

Notes

The bug only occurs when rendering the component directly from the controller. See: app/controllers/button_clicks_controller.rb. You can try visiting /fixed instead to view the same page, but with the component rendered from the view. This works as expected.
