maintenance_tasks UI not showing when config.intercept_erb = true

[sebaherrera07]

I recently introduced reactionview to my Rails web application (Ruby 3.4.6 and Rails 8.0.3).

In the same project, we have https://github.com/Shopify/maintenance_tasks, which is mounted as an engine that enables a route to be used via the UI.

When we enabled config.intercept_erb = true, that UI stopped working, it shows a blank page.

We have some other engines mounted for that project, such as https://github.com/ankane/pghero or https://github.com/rails/mission_control-jobs, and they load just fine.

Any ideas what may be the issue?

Hey @sebaherrera07, thanks for opening this pull request!

I guess the view has some sort of syntax error in the markup. If you open the browser inspect on the empty page, do you see these kinds of <template> tags?

Just opened Shopify/maintenance_tasks#1305 to address this.

Was about to open the PR myself when I saw your first comment and then I saw your second comment.

Thanks @marcoroth !
