/**
 * A special Ext.dom.Element used by Buttons.  Since buttons use `display:table` elements
 * for their layout, some special adjustments are needed when the width switches from
 * auto to fixed width and back.
 *
 * When the button has a width other than `auto`, and a right-aligned arrow, long button
 * text will cause the arrow to disappear off the right edge of the button if the btnWrap
 * element has table-layout:auto.  To prevent this, we need to set table-layout:fixed
 * on the btnWrap when the button has a width, however, when the button is shrinkwrap
 * width the btnWrap cannot have table-layout:fixed because its width:100% style will
 * cause the button to expand outward.
 *
 * Additionally, in shrinkWrap height mode, the button css sets a height on the btnEl
 * element, but if the height is being stretched, the btnEl's height will cause the contents
 * to be incorrectly vertically centered, so we dynamically set the btnEl's height to
 * "auto" in fixed-height mode.
