--- Comment #2 from Fujii Hironori <Hironori.Fujii at sony.com> ---
fast/text/emoji-single-parent-family.html has a similar issue.
��‍�� shows only the father glyph because ComplexTextController replaces the boy glyph with a space glyph.

ScriptShape

input text: [&#x1F468; ‍ &#x1F466;] (length=5)
output glyphs: [6368 6318] which are fater and boy glyphs
output clusters: [0 0 1 1 1] which means consisting two clusters, and the 0th cluster starts at glyphs[0] (father glyph), 1st cluster starts at glyphs[1] (boy glyph)

Then,

stringIndices: [0 2] which means glyphs[0] points to text[0], glyphs[1] points to text[2] (zwj).

ComplexTextController replaces the boy glyph with a space glyph because glyphs[0] (child glyph) points to zwj..
