status notifier icon keeps showing after dropping elevated privileges about mate-polkit HOT 4 CLOSED

Yes, for this reason i don't use libappindicator for fedora builds. For me libindicator status icon should be use the same behaviour than normal build.

I will try to debug this myself, if I am not successful I will also disable it in my builds. At the moment using it to work on a PR for the panel,
mate-desktop/mate-panel#583
at it showed that the new status-nofifier work does not include the panel menu theme support work I did two years ago, and thus menus come up mismatched if the theme sets a different panel menu theme (as mine does)

is a rough workaround for this. It quits the whole application and lets it respawn. This occurs only when build with appindicator support, the tray icon codepath is unchanged. NO PR as of now, but I am using it.

Mate-polkit from master works fine in gnome-panel, but mate-desktop/mate-panel@36c5430#diff-6ef0fc6b7e60a4b669e65fa5a7c84435 causes "passive" items to always show, and thus prevents the icon from being removed. I tested reverting this, and was even able to test for the icon name to limit it to mate-polkit, only to find that either permitted the icon to show and be removed once, then it would not show again. Would show again fine in gnome-panel, something didn't update correctly in mate-panel.

Thus, three possible fixes exist:
1: Special case this in the tray sn-notifier/tray applet and fix that failure to update. Best possible way, but I have no idea in the world where that failure to update on

2: Kill the whole app and let is respawn. Apparently the icon will persist as "passive" even after the app_indicator structure is unref'ed and nulled out, so long as the app is running.

3: Create an "null icon" of zero (or maybe 1x1 transparent?) pixel width and height so it does not take up space or show up but with a filename, and reset the icon to that on dropping privileges, then set it back if they are raised again. I tested setting the icon to NULL, but that hits an assertation, and setting the icon to an invalid name brpught up the missing icon icon. Downside here is some users might notice the tray being 1px wider after they have raised privileges oncel

Is anyone using mate-polkit from the command line or in one-shot start sessions? If so, I will rework this to use the empty icon that takes no space instead of stopping and restarting.

Finally found a way to fix this right, but this required changes in both mate-panel
mate-desktop/mate-panel#669
to hide this icon when passive and no others
and in mate-polkit
#38
to keep the same app_indicator alive so the icon could be shown more than once.
