Firefox esr is not supported [Bug]

[joschahenningsen]

Describe the bug
My os comes with the latest version of firefox esr (91.13.0esr) which was released in august: https://www.mozilla.org/en-US/firefox/91.13.0/releasenotes/ apparently the next esr release will be a 102.x upgrade but I suppose it might take a while to land.
With this version I get the error ReferenceError: structuredClone is not defined when opening navigatum. Presumably because the browser doesn't support some feature you use.

To Reproduce
Steps to reproduce the behavior:

1. Use Firefox 91.13.0esr
2. Open any room in navigatum

Expected behavior
The page should be displayed as intended.

Screenshots

Desktop (please complete the following information):

• OS: Debian GNU/Linux 11 (bullseye)
• Browser: firefox
• Version: 91.13.0esr (64-bit)

I just checked my updates after opening this issue. Turns out, 102.3.0esr is available now. 😄 🤦

Feel free to close this if you want, with the latest esr release it should not be too relevant anymore.

This will be fixed once the migration to Vue3 is complete (#200)
In the mean time I have no idea, why https://github.com/TUM-Dev/navigatum/blob/2f470660a6e27d6c9a7a9af6f6cfd9054364c520/webclient/src/core.js#L77 does not bloody work.
core is definitively included here https://github.com/TUM-Dev/navigatum/blob/2f470660a6e27d6c9a7a9af6f6cfd9054364c520/webclient/src/index.html#L53

@octycs any ideas?

Is defer the culprit?

@octycs any ideas?

I can also just guess ... maybe it has to do with the function declaration being in an if clause (see https://stackoverflow.com/a/10069457)? Then maybe window.structuredClone = function() { ... } could work.
