When deployed, HTML content inside a {{ #with }} is not displayed

Hi all,

this is a follow up on the question I created at Stackoverflow found here:

All the details in this link are still relevant. I thought I had fixed it, but still not.

Still, when I open the Configuration page, that has the form element enclosed in #with, sometimes the form shows up, sometimes it does not. I am not sure why.
Another thing as well, is that the data is not getting saved in the backend (using a method). When testing locally, it works just fine. The form is displayed and data gets saved.

But when running in my Gcloud instance, I am seeing this issue.

Has anyone ever seen this? I don’t know if it has anything to do with the way I am deploying to GCloud, with the docker container and such…
