Admin page translations missing after restart

[Foxi352]

After SHNG restart on the first connection to the admin interface the menu items do not translate.
After a page reload everything seems fine ...

That is a race condition in the frontend that I havn't found yet.

For the time being: Hit reload

In Vivaldi this sometimes resolves itself after a few seconds.

(mostly at the exact moment I initiate the reload...)

I tried reproducing this, which happens, but I haven't found a way to reliably reproduce it.

I did find a difference in the log:

on normal page load, the browser console shows

TopNavigationComponent.buildMenu: default_language de

while on failing loads, the messages are

TopNavigationComponent.buildMenu: default_language null
SharedService.getFallbackLanguage: private_fallback_language_order, set to Array(0: "en", 1: "de", 2: "xx")
TopNavigationComponent.buildMenu: default_language de
SharedService.getFallbackLanguage: private_fallback_language_order, set to Array(0: "en", 1: "de", 2: "xx")
ERROR TypeError: Cannot read properties of undefined (reading 'error')

So, in the second case, first no default language is set, and something seems to fail again on reading the fallback.

This doesn't solve anything, but for anyone familiar with the inner workings of the adminUI, this might serve as a pointer... (@msinn?)
