<div style="border: 1px solid black;"><span id="span" contenteditable="true">foo</span></div>

<script>
span = document.getElementById("span");
selection = window.getSelection();
selection.setPosition(span, 0);

document.execCommand("InsertText", false, "x");
document.execCommand("Delete");
document.execCommand("InsertText", false, "x");

document.execCommand("InsertText", false, "There shouldn't be any blank lines in the black bordered area.");
