1. Click "Create" button
2. Choose one content type, for example "Article", form is opened
3. Go back with web browser's "Back" button
4. Type a word in an input (menu of "Create" btn is still opened), make sure that nothing will be found.
5. Use "Enter" key and the application will go to create Article form again.

In addition: when you type something in input and close the "Create" button menu, the word you've typed is still there. Maybe this field should be cleared.
