Right click menu inside terminal doesn't show up can't copy

**Describe the bug**

I'm trying to highlight some text on the terminal window and then attempt to right-click to copy and proceed on however the menu that shows up in the right-click menu as if I did it on the Terminal Tabs, not the terminal itself therefore I'm unable to copy text.

**Expected behavior**

It should show the normal terminal right-click menu that you can see from the normal terminal app like this one

**Actual behavior**

Here is the menu that shows up when I right-click inside the guake terminal window

**To Reproduce**

1. Output some text in the terminal window of guake.
2. Highlight some text.
3. Attempt to right-click inside the "terminal window".
