Found comparing Microsoft's own specification documents with Word for
Windows: their tables of contents were a third taller in WordCraft
(13.4 pt per entry against Word's 10.9). Each entry's 9 pt text has tab
runs in an 11 pt font, and WordCraft sized the line by them.
Measured in Word with 13 synthetic documents: 11-20 pt tabs, spaces and
ideographic spaces next to 9 pt text leave the 9 pt line as it is,
wherever they are on the line; a line of only such whitespace takes the
paragraph mark's height; a big letter or no-break space does grow the
line. WordCraft now skips spaces and tabs when it sizes a line, and all
13 cases match.
