Might be hardware specific, i have a Logi MX master and i am using solaar with it.

Under system settings for Mouse, when activating "Press left and right button for middle-click", clicking these button together in the terminal only shows context menu.

But if you also activate the same option under the settings for touchpad "Press left and right button for middle-click", it works as intended.

STEPS TO REPRODUCE
1. Open system settings, make sure "Press left and right button for middle-click" is only activated under mouse
2. Open Yakuake select something and try to click Left & Right together, my result is context menu pops up.
3. Open system settings, make sure "Press left and right button for middle-click" is activated under both mouse and touchpad 
4. Repeat and it works as intended.
OBSERVED RESULT
Context menu shows

EXPECTED RESULT
Content should be copied to terminal
