coderpad.io disable blinking cursor

I am looking to disable the blinking cursor in coderpad.io I think its a codeMirror editor.

I am using CSS

.CodeMirror-cursor, div.CodeMirror-cursor {
    opacity: 1;
    display: none;
}

But this removes the cursor altogether. I cant find a way to make the cursor visible but stop the annoying blinking
