SUMMARY
Take Remmina RDP client for example (since I can reproduce on it), it has a protocol drop down list, RDP, VNC, SSH and X2GO. 
As shown in the attached screenshot, the drop down thinks it's long and wraps itself, but it's actually short.
This issue isn't frequent, and I can reproduce it on Deluge GTK client's ltconfig drop down list too. Given the fact that Remmina is a GTK client, i think it's related to KDE's GTK implementation.


STEPS TO REPRODUCE
1. Open Remmina
2. Click RDP to drop down the list

OBSERVED RESULT
The list wraps

EXPECTED RESULT
Shouldn't wrap as it's short and has only 4 items.
