SUMMARY
Using the Paste function in the terminal of "F4 mode" opens a new right-click menu when the "Paste" command is positioned in the "folder" part.

STEPS TO REPRODUCE
1. Open a folder in Dolphin
2. Press the F4 button to show the terminal in the bottom part of the windows
3. Right-click in the terminal -> Paste

OBSERVED RESULT
When the "Paste" command is shown over the terminal part, it works fine and the content is pasted
When the "Paste" command is shown over the FOLDER part, it paste the content then immediately shows a new "right click menu"

In the attached video, you can see the first "paste" command work as expected because the "Paste" is positioned over the terminal. The last paste immediately opens a new menu. The trigger seems to be the Paste command positioned in the folder (white) part of the window. 

I had the same problem on Kubuntu 25.10, but I didn't report it because it was an "old" plasma version. Now I switched to CachyOS and it's still there.

EXPECTED RESULT
The new menu should not be shown because it blocks the user typing on the keyboard
