Since a few days (may be since the latest update, I am not sure) the comments popup behaves differently when it is closed with the Escape key. I have been using the comment function for years, and I am used to close the popup with the Escape key. But now, any changes are not stored, when using this key. I have to explicitly hit the button in the popup (labeled "Beitragen" in the German version, may be "Comment" or "Contribute" in the English version).
Is there any setting in the preferences where I can restore the old behavior? Is there another keyboard shortcut to close the popup and to store the changes?
