AX: Add layout tests for the text marker index space over emoji and invisible
characters
https://bugs.webkit.org/show_bug.cgi?id=323360
rdar://186603195
Reviewed by Chris Fleizach.
bounds-for-range-multibyte-glyphs.html already captures the code unit span of a
joined
emoji and a variation-selector emoji, by asserting the rect boundsForRange
returns for
each. It never reads the string and never uses the index APIs, so what is new
below is
the index round trip and the presence of the invisible characters themselves.
text-marker-index-regional-indicators.html:
No accessibility test contains a regional indicator. A flag is four code units
and two
code points in one glyph, stressing surrogate pairs and cluster boundaries
together.
text-marker-index-zwj-sequence.html:
Asserts the zero width joiner survives into the accessibility text at its own
index.
The bounds test shows an eleven code unit span is treated as one glyph but
cannot show
the joiner is still in the string. Without it, an assistive technology
reconstructing
the sequence from character offsets gets two unrelated emoji.
text-marker-index-variation-selector.html:
Same for a variation selector, which is invisible and only changes how the
preceding
character is drawn. Asserting its code point is the only way to tell it was
preserved
rather than folded into the character it modifies.
