Tab width calculation in WidthIterator and ComplexTextController uses Font::tabWidth(), which is based on Font::spaceWidth(). When the specified font lacks a space glyph, spaceWidth() will be 0 or otherwise wrong. Instead, the width of the space glyph from the fallback font should be used. Patch forthcoming.
