When letting the IDE perform a fix by inserting an import statement (in this case java.net.Socket), the text
input cursor disappears. It's no longer possible to enter any code into the editor. It is possible to move
around in the code with the mouse (line and column numbers at the bottom change when clicking), as well
as making selection, but it's not possible to enter text or perform any actions via the keyboard.

It's duplicate of issue 65326. Unfortunatelly it's JDK bug.
