The trash icon is not updated when deleting a file in Dolphin and then emptying the trash using the desktop icon.

Steps to reproduce:
1) Open Dolphin, create a new text file
2) Delete the text file: trash icon is updated to 'contains trash'
3) Empty the trash using the trash icon on the desktop
4) Trash is emptied but the icon remains in the 'contains trash' state

I'm using Breeze-Dark but it happens regardless of the icon theme. When i create and delete the file on the desktop (instead of Dolphin) it works as expected.

There is an old bug describing the same issue: https://bugs.kde.org/show_bug.cgi?id=249725

I'm not sure what the right category for this is, so feel free to move if it doesn't belong to plasma shell.
