The new DirectWrite implementation for OpenGL rendering seems to be mispositioning glyphs for multi-byte codepoints drawn from SMP or higher.

Multiple glyphs are being positioned a top each other when a glyph from the SMP is selected--either the Special Character dialog or as a bracketed :emoji: autocorrect entry.

Using glyphs for BMP codepoints does not cause the misplacement, but they are affected once a glyph from the SMP is inserted onto a line.

@Tor, should this be closed duplicate of bug 97319 cmts 9-10?
