[snap] No access to user config directory for separate app IDs

[hackel]

After the forced upgrade to the snap version of Chromium, all of my Chrome app shortcuts stopped working.

I have several apps which I launch like this:
chromium-browser --user-data-dir=/home/hackel/.config/appname --profile-directory=Default --app-id=abcdjdachboclehgmhnocadmlnkmehhi

They are now all broken.

So I can move my user-data-dir into ~/snap/chromium/current/.config and that works fine, but what do I do about the custom icons? These were created in e.g.
~/.local/share/icons/hicolor/*/apps/chrome-abcdjdachboclehgmhnocadmlnkmehhi-Default.png
for all 5 different icon sizes. But the corresponding snap icon directories are all broken symlinks to /snap/chromium/881/data-dir/icons/hicolor/64x64. (There actual directory structure ends with an empty icons directory.) A snap running as a user wouldn't be able to write to those directories anyway, right? Or does snapd have some mechanism to allow that?

If I try to use the Create Shortcut function in Chromium, I get this error 14 times:
LaunchProcess: failed to execvp:
xdg-desktop-menu

It doesn't actually create any .desktop or icons that I can find anywhere on the filesystem.

Is there time to restore the old deb package? This snap is just *not* ready for prime time!
