Exports warn about type in a symbol's art that is set in a missing
font and point to Find Font, but Find Font and Replace Missing Fonts
only looked at the type on the layers.
- text.fonts lists the fonts of the type in the document's symbols too;
with selectionOnly, of the symbols the selected instances show.
- select.font (Find) also selects the instances of the symbols whose
art uses the font in type that is not hidden or locked.
- text.replaceFont changes that type in the symbols in scope, so every
instance follows. Type hidden or locked in a symbol's art, and the
type of symbols that only a selected hidden or locked instance shows,
keeps its font and is counted in skipped.
- addon.cleanup.replaceFonts replaces missing fonts in symbols' type.
While a symbol is edited, its type is taken from the editing layer
only, so it is counted and changed once.
