Icons doesn't show on dock

[QkiZ]

When I'm connecting to ssh with Remmina window appears but theres no icon on dock/launcher. I see window and I can navigate to it by alt+tab but icon on dock/launcher is missing. I need to restart Gnome by alt+f2 and type `r` to see missing icon.
* Client: Ubuntu 18.10
* Remmina version: 1.2.31.4
* Desktop environment: Gnome
* Connecting to: Ubuntu Server 18.04
* it's problem with application, not connection.

Thank you for your bug report. Do you get the issue very time? Is the icon listed in the overview screen (the one you get my clicking on the activity corner in the top left)? Could you add your journalctl log to the bug after getting the issue?

Here is syslog: https://paste.ubuntu.com/p/XHM9DymqDK/
And here are messages from Remmina when I ran it from the command line.

StatusNotifier/Appindicator support: your desktop does support it and libappindicator is compiled in remmina. Good!
Running under Gnome Shell version 3.30.2

(remmina:23036): Gtk-WARNING **: 11:47:48.289: gtk_menu_attach_to_widget(): menu already attached to GtkMenuItem

This happens from time to time. Sometimes icon appears on dock, sometimes not.

Thank you for your bug report, could you make a screencast showing the issue (or at least a screenshot). Do you close the main windows? How do you open the connection and what options do you select? It works fine here
