Konsole doesn't search $XDG_CONFIG_DIRS for konsolerc

Konsole successfully searches $XDG_DATA_HOME (~/.local/) then
$XDG_DATA_DIRS (~/usr/share/my-distro-package/) for its konsole/ data
directory, finding my `Shell.profile`, which is for my distro's users

The problem is `.konsolerc`. Konsole searches $XDG_CONFIG_HOME (~/.config/)
for .konsolerc. If it doesn't find it there (which it won't upon first
use), it *should* then search $XDG_CONFIG_DIRS. However, it does not.
Instead it creates a default `.konsolerc` in $XDG_CONFIG_HOME. I even did
`chmod -rw .konsolerc`. This makes Konsole complain, but it will never find
my distro's .konsolerc via $XDG_CONFIG_DIRS.

There's more strangeness: There seems to be a "hidden" config file
somewhere for Konsole. If I go into Konsole settings, I can see that
Shell.profile is listed. Despite being the only profile, it is not used by
default. Instead, some hardcoded profile named "Default" is used. The
weirdness? If I set Shell.profile to be the active and default profile, I
can see that this change is written to `~/.config/konsolerc`. If I then
delete `~/.config/konsolerc` and restart Konsole, `Shell.profile` is still
active! (This misled me while debugging).

Note: `Shell.profile` simply enables unlimited scrollback. I want this to
be the default upon bootup for our users, configured via XDG and not
/etc/skel or by changing files in ~.
