I installed a browser extension which shows me which site elements are served with a PQ-safe KEX. This made me aware that some elements in the Zigbee2Mqtt frontend are loaded directly off a remote server from the internet. See this screenshot top right:

I guess kudos for using PQ-safe KEX. Same info is available via browser's developer console. This seems to be how feature
#53 is implemented.
Describe the solution you'd like
Instead of letting the web browser load the images of the zigbee devices from an online service, download them to the Zigbee2Mqtt instance and serve them locally so they stay available even without internet connection.
Describe alternatives you've considered
It could stay like it is now. But the current solution seems a bit hacky.
Additional context
Sample files (depends on what you're using):
