When calculating the width of an InlineTexBox using simplified measuring, we simply sum up the width of every glyph. Some fonts (at least FreeType fonts) specify the non-zero width of `Zero Width Joiner`, `Zero Width Non-Joiner`, and `Zero Width No-Break Space`. Later, during the rendering, these glyphs are skipped causing the `InlineTextBox`es to become wider than they should be.
