copy paste clipboard does not sync up with system clipboard

[digtail]

Describe the bug

copy and paste outside nheko works fine. when I copy something, I can paste it inside nheko. when I copy text in the message textbox using ctrl-v I can paste it in other applications. however, when I select a message, right click and press "copy", I can only paste it inside nheko. if I paste outside, whatever was in the clipboard before gets pasted.

copy and paste between nheko and other apps does not work

To Reproduce

1. open a chat in nheko
2. open another app with text box
3. select a message in nheko and click "copy" in the contex menu
4. copy some text in the other app
5. paste in nheko -> the selected message from (3.) gets pasted
6. paste in the other app -> the text from (4.) gets pasted (expected behaviour for (5.))
7. once again, select a message in nehko and click "copy" in the context menu
8. paste in the other app -> the text from (4.) gets pasted (expected text from (7.) to get pasted)
