Summary: Helvetica's zero-width space glyph has non-zero width. WebKit should ignore this and render it as zero-width.

Note that this is a valid issue (and cannot be dismissed as a bug in the font) because (1) the simple text rendering code path replaces certain non-printing characters with the zero-width space glyph and (2) the complex (ATSUI) code path actually does force ZWS to have zero width regardless of the font (so there is inconsistency between the code paths).
