373  added to every line instead of only a distance between multiple lines,
374  which means a single bullet has external leading added even though it
375  shouldn't, but frankly this is just an educated guess rather than understanding
376  Writer's layout (heh).
377  Symbol font in some documents is 'StarSymbol; Arial Unicode MS', and Windows
378  machines often do not have StarSymbol, falling back to Arial Unicode MS, which
379  has unusually high external leading. So just reset external leading for fonts
380  which are used to bullets, as those should not be used on multiple lines anyway,
381  so in correct rendering external leading should be irrelevant anyway.
382  Interestingly enough, bSymbol is false for 'StarSymbol; Arial Unicode MS', so
