Fix flipout container not work

Forum member NNI has reported that if type "shift+ctrl+c" in a sakura terminal, inside a container, to copy selected text to the clipboard, it then broke flipout of the container.

Found a fix, reported here:

That's good, because other people have reported this problem previously, and we never determined why.
