Topicons Plus broken with the 3.28 release
As advised in the 3.26 release notes I'm using the Topicons Plus extension to keep apps which need legacy trayiocns upport working.
I use hexchat as irc-client with the following options under Settings -> Preferences -> Chatting -> Alerts enabled:
Enable System Tray Icon Minimize to tray Close to tray
This allows me to keep my irc out of the way while still getting notifications for pings. When clicking the hexchat icon which shows up in the top-bar the entire hexchat window is hidden or shown.
After upgrading to F28 I noticed that this no longer work, if I minimized the hexchat window (which also hides it with these options) I can no longer unminimize it by clicking the trayicon.
This seems to be a focus or event handling problem, the first time I hover my mouse over the icon it properly highlights and if I then right or left click during the first time the mouse is over the icon, it the expected action happens. If I move the mouse away and then move it over the icon again, the icon no longer highlights and clicks are ignored.
I'm only seeing this with the default GNOME (on wayland) session. This problem does not happen with the "GNOME on Xorg" session.
