+ An overflow condition applies when the bounding box of some descendant line area extends outside of the containing
+ region's nominal content area extent in either or both 1) the inline and 2) the block progression dimensions, where
+ the nominal content area extent in both dimensions is determined by the computed values of the <code>tts:extent</code>
+ and <code>tts:padding</code> style properties of the containing region. Overflow in the inline progression dimension
+ can occur only if <code>tts:wrapOption</code> is <code>noWrap</code>.
Furthermore, when an overflow condition applies, it is not intended that the effective extent of the region be modified for the purpose of presentation processing.
For example, the area painted with the region's background color is not extended in either dimension to enclose the overflowed content.</span></p>
