Yeah I think for the problem you described is related to the trusted hosts.

When streamlit loads make a request to the backend and gets all the hosts that are trusted to execute code remotely with window messages. So I added localhost as a trusted host. By default streamlit only adds its own servers. In fact you will have to modify in order to work with your own host domains.

First time loads send default host, on second reload it will work, it's only first time. This it is the only way to make it works with a technique call it Cross Origin Injection or COI. This adds JavaScript listener that listen to python messages and give the capability to execute JavaScript in streamlit apps.

But I will check it because streamlit makes a lot of changes between different versions.
