cursor invisible in column 0

[cben]

The cursor is invisible when at left-most position.

codemirror.css sets:

.CodeMirror pre {
  padding: 0 4px; /* Horizontal padding of content */
}

This is overridden by my renderLine callback for indented soft-wrapping, it sets style="text-indent: -0ex; padding-left: 0ex;" on the pre element :-(
