SUMMARY


STEPS TO REPRODUCE
1.  Open dolphin and enable the terminal panel.
2.  Don't resize the terminal panel. Make sure dolphin is maximized to full screen such that the context menu goes up the mouse cursor
3.  Write something in the terminal. Select the text and right click with the mouse to copy. See the new context window pop up.
4. Now resize the terminal to a bigger size such that the context window shows below the cursor. Repeat the process in step 3 and notice another context window doesn't show up now after pressing copy

OBSERVED RESULT
 
Write something in dolphin the terminal. Select the text and right click with the mouse to copy. See the new context window pop up. This is observed when the context window goes up the cursor, which spawns another context window when copy is clicked with mouse button.

EXPECTED RESULT

Another context window should not appear when copy is clicked on a text in the dolphin terminal.
