Bug: middle mouse button: Option "Close all"

[Golddouble]

This is a bug report about docklike version 0.4.1

System: MX-Linux 19 (Debian 10 based)

I have used docklike version 0.4.0 before. With the new docklike 0.4.1 I have still all issues I hade with docklike 0.4.0 but in addition one issue more.

Here is a bug report about the new issue which I did not have with docklike 0.4.0:

These are my settings:

Issue: I can not close programmes by clicking on the icon in docklike with the middel mouse button.

How to reproduce:

1. Pin Featherpad into Docklike
2. open Featerpad by clicking on the icon in docklike
3. copy or write some text into the Featherpad window (do not save)
4. press the middle mouse button on the Featherpad icon in docklike

Expected behaviour:
It will ask, if it should save the changes.

Actual behaviour:
At the same time it asks, if it should save the changes and at the same time it opens a second Featherpad window.
