Word kerns nothing unless w:kern names a size to start at, and the Office
theme declares it on Title alone — but TextProps.kerning stored only the
off state, and a style inherits its parent's, so a title under a document
that kerns nothing could never turn it back on. Its 26pt line then ran
0.36mm over the text width and wrapped a word onto a second line where
LibreOffice sets it in one (measured 151.64mm kerned against 151.98).
Both states are stored now, and both formats read and write them.
