/**
 * Test for ensuring page doesn't jump up to the Table selection on IE with
 * these steps:
 *
 * <p>
 * 1. refresh page <br>
 * 2. click within URL bar <br>
 * 3. click a table row to select it <br>
 * 4. click within one of the text fields <br>
 * 5. scroll down <br>
 * 6. click the button
 * </p>
 * The problem is that IE for some reason does not fire a blur event for the
 * table at step 4, leading to table thinking it is focused when it is updated
 * in step 6.
