Buttons update unexpectedly (mouseout)

[CynderR]

With the WYSIWYG editor, if you select outside of the text area and then mouse over the WYSIWYG area, the buttons update to show the state of whatever the current selection is. This is because of
editor.attr('contenteditable', true).on('mouseup keyup mouseout', function () {
Removing the mouseout from that line fix's the issue, but im not sure if it breaks some functionality.
