When self-hosted, manifest is missing when installing PWA on iOS

[Hodapp87]

Describe the bug

When on iOS, PWA doesn't work properly on self-hosted Organice - that is, built and served from my own nginx, or bin/entrypoint.sh. (Not tested on Android yet.)

This problem goes away if:

• I use https://organice.200ok.ch instead of my self-hosted installation.
• I manually copy https://organice.200ok.ch/manifest.json to my installation's web root.

In digging a little: index.html contains /manifest.json here as the manifest the PWA needs - but this manifest.json isn't present anywhere in the repository or build.

However, the script in index.html then rewrites this manifest's href to that of a JSON blob created in the script. If I use a desktop browser, the manifest then seems to be visible, e.g. if I go to Developer Tools, Application, & Manifest, the proper JSON is visible.

Does iOS refuse to run the script when installing as a PWA, or something like that? I suspect someone was aware of this, which is why https://organice.200ok.ch/manifest.json exists.

To Reproduce

Steps to reproduce the behavior:

1. Set up Organice to be self-hosted, e.g. with nginx.
2. Follow the iOS instructions at https://organice.200ok.ch/documentation.html#installation - using the URL of the self-hosted Organice, not https://organice.200ok.ch.
3. Press the icon just created on the home screen.

Organice will just open as a tab in the default browser - not as a PWA. iOS appears to be treating it just as a bookmark.

Expected behavior
It's expected that Organice opens as a PWA - not just a Safari tab/bookmark.
