signal-desktop: private-etc @tls-ca breaks opening links under Plasma (kio)

[ilikenwf]

Description

Links only open if private-etc is ignored. This is an fyi in case there's a less heavy handed approach than just ignoring private-etc.

The breaking line is private-etc @tls-ca

less heavy handed approach than just ignoring private-etc.

The following should show which paths in /etc are used:

firejail --trace=trace.txt /usr/bin/signal-desktop

What is the output in trace.txt when running the command with and without
private-etc?
