- * Returns the "offsetStart" of an element, analagous to offsetLeft but

- * inconsistencies. This value returned can always be passed to setScrollOffset
- * to scroll to an element's left edge in a left-to-right offsetParent or
- * right edge in a right-to-left offsetParent.
- *
- * For example, here offsetStart is 10px in an LTR environment and 5px in RTL:

- * |          xxxxxxxxxx     |
- *  ^^^^^^^^^^   ^^^^   ^^^^^
- *     10px      elem    5px
- * </pre>
- *
- * If an element is positioned before the start of its offsetParent, the
- * startOffset may be negative.  This can be used with setScrollOffset to
- * reliably scroll to an element:
- *
- * <pre>
- * var scrollOffset = goog.style.bidi.getOffsetStart(element);
- * goog.style.bidi.setScrollOffset(element.offsetParent, scrollOffset);
- * </pre>
- *
- * @see setScrollOffset
- *
- * @param {Element} element The element for which we need to determine the
- *     offsetStart position.
- * @return {number} The offsetStart for that element.
